Construction of multiple switchable sensors and logic gates based on carboxylated multi-walled carbon nanotubes/poly(N,N-diethylacrylamide)

In this work, binary hydrogel films based on carboxylated multi-walled carbon nanotubes/poly(N,N-diethylacrylamide) (c-MWCNTs/PDEA) were successfully polymerized and assembled on a glassy carbon (GC) electrode surface. The electroactive drug probes matrine and sophoridine in solution showed reversible thermal-, salt-, methanol-and pH-responsive switchable cyclic voltammetric (CV) behaviors at the film electrodes. The control experiments showed that the pH-responsive property of the system could be ascribed to the drug components of the solutions, whereas the thermal-, salt-and methanol-sensitive behaviors were attributed to the PDEA constituent of the films. The CV signals particularly, of matrine and sophoridine were significantly amplified by the electrocatalysis of c-MWCNTs in the films at 1.02 V and 0.91 V, respectively. Moreover, the addition of esterase, urease, ethyl butyrate, and urea to the solution also changed the pH of the system, and produced similar CV peaks as with dilution by HCl or NaOH. Based on these experiments, a 6-input/5-output logic gate system and 2-to-1 encoder were successfully constructed. The present system may lead to the development of novel types of molecular computing systems.

Electrochemical monitoring of reactive oxygen/nitrogen species and redox balance in living cells

Levels of reactive oxygen species (ROS) and reactive nitrogen species (RNS) in cells and cell redox balance are of great interest in live cells as they are correlated to several pathological and physiological conditions of living cells. ROS and RNS detection is limited due to their spatially restricted abundance: they are usually located in sub-cellular areas (e.g., in specific organelles) at low concentration. In this work, we will review and highlight the electrochemical approach to this bio-analytical issue. Combining electrochemical methods and miniaturization strategies, specific, highly sensitive, time, and spatially resolved measurements of cellular oxidative stress and redox balance analysis are possible. [Figure not available: see fulltext.].

Metathetical reactions of Re(VII) alkylidene-alkylidyne complexes of the type Re(CR?)(CHR?)[OCMe(CF3)2]2 (R? = CMe3 or CMe2Ph) with terminal and internal olefins

1-Decent and methyl 9-decenoate react with syn- and anti-Re(C-t-Bu)(CH-t-Bu)(ORF6) to give syn- and anti-Re(C-t-Bu)[CH(CH2)7Me](ORF6)2 and syn- and anti-Re(C-t-Bu)[CH(CH2)7CO2Me](OR F6)2, respectively (ORF6 = OCMe(CF3)2). The new alkylidene complexes are unstable in the presence of excess terminal olefin and decompose upon attempted isolation. However, vinylferrocene reacts relatively smoothly and reversibly with syn-Re(C-t-Bu)(CH-t-Bu)(ORF6)2 in a noncoordinating solvent to yield tert-butylethylene and primarily anti-Re(C-t-Bu)(CHFc)(ORF6)2 (Fc = ferrocenyl). anti-Re(C-t-Bu)(CHFc)(ORF6)2 (a = 9.769 (2) A, b = 30.746 (7) A, c = 10.140 (2) A, beta = 116.78 (1), V = 2719 (2) A3, space group = P21/a, Z = 4, FW = 815.50, p(calcd) = 1.992 g/cm3, R = 0.052, Rw = 0.050) was shown to be a pseudotetrahedral species with an unusually acute Re=Calpha – Cbeta angle (114.8 (7)) and short Re=C bond (1.70 (1) A). In the presence of THF or dimethoxyethane, complexes of the type syn- or anti-Re(C-t-Bu)(CHR)(ORF6)2S2 (R = Me, Et, Ph; S = THF or 0.5DME) could be prepared in high yield from Re(C-t-Bu)(CH-t-Bu)(ORF6)2 and CH2=CHR. Heteroatom-substituted (O, S, or N) terminal olefins react more rapidly than ordinary olefins with Re(C-t-Bu)(CH-t-Bu)(ORF6)2 in the presence of THF to yield complexes of the type syn- or anti-Re(C-t-Bu)(CHX)(ORF6)2(THF)2 (X = OR, SR, NR2, or p-dimethylaminophenyl). The X-ray structure of syn-Re(C-t-Bu)(CHOEt)(ORF6)2(THF)2 (a = 10.318 (1) A, b = 18.303 (2) A, c = 16.181 (2) A, beta = 96.98 (2), V = 3033 (1) A3, space group = P21/c, Z = 4, FW = 819.74, rho(calcd) = 1.795 g/cm3, R = 0.052, Rw = 0.050) showed it to be a pseudooctahedral complex containing cis alkylidyne and alkylidene ligands and a THF ligand trans to each. The Re-O bond to the THF trans to the neopentylidyne ligand is significantly longer than that trans to the ethoxymethylene ligand; presumably it is the THF ligand trans to the neopentylidyne ligand that exchanges more rapidly with free THF in solution. 2-Pentene or methyl oleate is metathesized in the presence of Re(C-t-Bu)(CH-t-Bu)(ORF6)2, and intermediate alkyidene complexes can be observed in each case. Addition of 3-hexene to Re(C-t-Bu)(CH-t-Bu)(ORF6)2 followed by TMEDA yields Re(C-t-Bu)(CHEt)(ORF6)2(TMEDA). Internal olefins are metathesized only very slowly by Re(C-t-Bu)(CH-t-Bu)(ORF6)2 in the presence of several equivalents of THF or DME or especially in neat THF or DME.

IR spectral and X-ray single crystal study of hydrogen bonds and structure of nonamethylferrocenyl- and ferrocenylcarbinols in the solid state

The influence of different substituents in the Cp-ring and at the carbinol C atm on the character and stability of H bonds in crystals of FcCHROH and 9FcCHROH, Fc = C5H5FeC5H4; 9Fc = C5Me5FeC5Me4, (R = H, CH3, C6H5, C6F5) was studied by IR spectroscopy specifically in the nu(OH) region.In the crystals, molecules associate predominantly via intermolecular OH…O bonds.However, in some of the 9FcCHROH complexes, the intermolecular O-H…?(Cp) H bonds are also formed.The major type of self-association in compounds with R = Mes is OH…?(Mes) H-bonding.It was found from the X-ray structural data for the 9FcCHMesOH that the Mes plane is almost perpendicular to each Cp ring plane.No intermolecular OH…O bonds are formed because of intramolecular shielding of the OH group.The stability of the intermolecular hydrogen bonds is determined by steric rather than electronic factors, the most stable intermolecular hydrogen bonds being formed in the case of primary carbinols.

Synthetic Route of 1271-48-3, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 1271-48-3, Name is 1,1′-Ferrocenedicarboxaldehyde,introducing its new discovery.

24- and 26-membered macrocyclic diorganotin(IV) bis-dithiocarbamate complexes with N,N?-disubstituted 1,3- and 1,4-bis(aminomethyl)benzene and 1,1?-bis(aminomethyl)ferrocene as spacer groups

The potassium bis-dithiocarbamate (bis-dtc) salts of 1,3- bis(benzylaminomethyl)benzene (1,3-Bn-ambdtc), 1,3-bis(iso-butylaminomethyl) benzene (1,3-iBu-ambdtc), 1,4-bis(benzylaminomethyl)benzene (1,4-Bn-ambdtc), and 1,4-bis(iso-butylaminomethyl)benzene (1,4- iBu-ambdtc) were reacted with three different diorganotin dichlorides (R2SnCl2 with R = Me, nBu, and Ph) in 1:1 stoichiometric ratios to give the corresponding diorganotin bis- dithiocarbamates. Additionally, the dimethyltin bis-dithiocarbamate of 1,1?-bis(benzylaminomethyl)ferrocene (1,1?-Bn-amfdtc) was prepared. The resulting complexes have been characterized as far as possible by elemental analysis, FAB+ mass spectrometry, IR and NMR (1H, 13C, and 119Sn) spectroscopy, and single-crystal X-ray diffraction, showing that the tin complexes are dinuclear 24- and 26-membered macrocyclic species of composition [{R2Sn(bis-dtc)}2]. As shown by 119Sn NMR spectroscopy, the tin centers are hexa-coordinated in all cases; however, two different coordination environments are possible, as detected by single-crystal X-ray diffraction. In the dimethyltin derivatives of 1,3-Bn-ambdtc, 1,3-iBu-ambdtc, 1,4-Bn-ambdtc, and 1,1?-Bn-amfdtc and the di-n-butyltin derivative of 1,3- iBu-ambdtc, the metal atoms are embedded in skewed-trapezoidal- bipyramidal coordination polyhedra with asymmetrically coordinating trans-oriented dtc groups. In contrast, in the diphenyltin derivative 1,3- iBu-ambdtc, the metal centers have distorted octahedral coordination with symmetrically coordinating cis-oriented dtc functions. Thus, for the complexes derived from 1,3-Bn/iBu-ambdtc, two different macrocyclic structures were observed. In the dimethyl- and di-n-butyltin derivatives, the bridging bis-dtc ligands adopt U-shaped conformations, while in the case of the diphenyltin derivative, the conformation is L-shaped. Furthermore, two different macrocyclic ring conformations can occurr, which differ in the spatial orientation of the substituents attached to the nitrogen atoms (Bn or iBu). The dimethyltin derivatives of 1,4-Bn-ambdtc and 1,1?-Bn-amfdtc have cavities, in which aromatic rings are accomodated in the solid state.

Substituent effects on ferrocenes in aluminum chloride-butylpyridinium chloride molten-salt mixtures

The visible absorption spectra and reduction potentials of 11 ferrocenes containing electron-withdrawing substituents were determined in an N-n-butylpyridinium chloride-aluminum chloride molten salt. When the substituent(s) on the cyclopentadienyl ring(s) of ferrocene were varied, the reduction potential was caused to range over 1.25 V, and the wavelength for maximum absorption of visible light was varied by nearly 200 nm. These changes are greater than have been observed for similar ferrocenes in other nonaqueous solvents. Evidence is presented for specific interactions of particular ferrocenes with the molten salt.

A Feedback Control Approach to Organic Drug Infusions Using Electrochemical Measurement

Goal: Target-controlled infusion of anesthesia is a closed-loop automated drug delivery method with a computer-aided control. Our goal is to design and test an automated drug infusion platform for propofol delivery in total intravenous anesthesia (TIVA) administration. Methods: In the proposed method, a dilution chamber with first-order exponential decay characteristics was used to model the pharmacodynamics decay of a drug. The dilution chamber was connected to a flow system through an electrochemical cell containing an organic film-coated glassy carbon electrode as working electrode. To set up the feedback-controlled delivery platform and optimize its parameters, ferrocene methanol was used as a proxy of the propofol. The output signal of the sensor was connected to a PI controller, which prompted a syringe pump for feedback-controlled drug infusion. Results: The result is a bench-top drug infusion platform to automate the delivery of a propofol based on the measurement of concentration with an organic film-coated voltammetric sensor. Conclusion: To evaluate the performance characteristics of the infusion platform, the propofol concentration in the dilution chamber was monitored with the organic film-coated glassy carbon electrode and the difference between the set and measured concentrations was assessed. The feasibility of measurement-based feedback-controlled propofol delivery is demonstrated and confirmed. Significance: This platform will contribute to high-performance TIVA application of intravenous propofol anesthesia.

Ferrocenylalkylation processes under electrospray ionization conditions

The electrospray ionization behavior of some ferrocenylalkylazoles CpFeC5H4CH(R)Az (AzH are derivatives of imidazole, pyrazole, triazole and their benzo analogs; R = H, Me, Et, Ph), ferrocenylalkanols CpFeC5H4CH(R)OH (R = H, Me), and mixtures of the latter with azoles was studied. The electrospray ionization mass spectra of these compounds, in addition to the molecular ion [M] +¡¤, the protonated molecule [M + H]+, and ferrocenylalkyl cation [FcCHR]+ peaks, exhibit also intensive peaks for the binuclear ions [(FcCHR)2X]+ (X = Az or O), resulting from ferrocenylalkylation of the initial compounds with the ferrocenylalkyl cations. Electrospray ionization of an equimolar mixture of ferrocenylmethanol FcCH2OH and imidazole gives the protonated ferrocenylmethylimidazole molecule [FcCH2Im + H]+ and the [FcCH2(Im)2 + H]+ dimer, apart from the ions typical of each component, i.e., ferrocenylalkylation of azoles with the ferrocenylalkylcarbinols, known in the chemistry of solutions, takes place under electrospray conditions.

Ferrocene-appended iridium(III) Complexes: Configuration regulation, anticancer application, and mechanism research

A series of ferrocene-appended half-sandwiched iridium(III) phenylpyridine complexes have been designed and synthesized. These complexes show better anticancer activity than cisplatin widely used in clinic under the same conditions. Meanwhile, complexes could effectively inhibit cell migration and colony formation. Complexes could interact with protein and transport through serum protein, effectively catalyzing the oxidation of nicotinamide-adenine dinucleotid and inducing the accumulation of reactive oxygen species (ROS, 1O2), which confirmed the anticancer mechanism of oxidation. Furthermore, laser scanning confocal detection indicates that these complexes can enter cells followed by a non-energy-dependent cellular uptake mechanism, effectively accumulating in the lysosome (Pearson’s colocalization coefficient: ?0.90), leading to lysosome damage, and reducing the mitochondrial membrane potential (MMP). Taken together, ferrocene-appended iridium(III) complexes possess the prospect of becoming a new multifunctional therapeutic platform, including lysosome-targeted imaging and anticancer drugs.
