Noncovalent linkage of telechelic oligo(dimethylsiloxanes) via end group attachment of host-cyclodextrins and guest-adamantanes or guest-ferrocenes

In this article, we report the noncovalent linkage of terminal substituted oligo(dimethylsiloxanes) bearing cyclodextrins (CD) as host endgroups and adamantan or ferrocene, respectively, as guest endgroups. Structural characterization was performed by 1H NMR-, IR-, and mass spectroscopy. Electron microscopy studies show significant differences in the surface structure of the individual derivatives. In addition, the ferrocene-terminated di-and poly(dimethylsiloxanes) are distinguished by a red-ox activity and reversibility, which also makes the complexes between the ferrocene- and CD functionalized siloxanes switchable via electrochemical stimuli. The evidence for a successful complexation of the end groups, and thus the successful supramolecular formation of the siloxane strands, was even performed by shift of the protons in the 1H NMR spectra.

Conformational analysis of ferrocene-containing alcohols. A density functional study of weak OH…Fe interactions

Optimized geometries and vOH stretching frequencies are reported for a set of monosubstituted ferrocenes, Fe(C5H5)(C 5H4R) [R = (CH2)nOH (n = 1-4), CH(Me)OH, CH(tBu)OH], at the BP86 level of density functional theory. In addition, NMR chemical shifts have been computed at the GIAO-B3LYP level. In all species studied, the most stable conformer is characterized by an OH…Fe moiety with Fe…H distances in the region between 2.61 and 2.95 A, followed by conformers with OH…pi interactions involving the C(ipso) atoms of the cyclopentadienyl ring. According to population and topological (Bader) analyses of the electron density, these conformers are stabilized by weak electrostatic interactions, rather than by true intramolecular hydrogen bonds. The VOH stretching frequencies are a very sensitive probe for the OH…Fe interaction, and the observed red-shift of this band relative to isomers with “free” OH bonds, which can exceed 100 cm-1, is well reproduced computationally. When other H-bond acceptors are present, the intramolecular OH…Fe interaction cannot compete with intermolecular H-bond formation, as has been explicitly shown in a Car-Parrinello molecular dynamics (CPMD) simulation of Fe(C5H5)-(C 5H4CH2OH) in water. Compared to these unconstrained ferrocene-containing alcohols, somewhat stronger OH…Fe interactions can be present in ansa derivatives, e.g., in a [2]ferrocenophane derivative with a CH2CH2OH group, for which a bond path between Fe and the alcoholic H atom is found.

Influence of macroporous gold support and its functionalization on lactate oxidase-based biosensors response

A general bioanalytical platform for biosensor applications was developed based on three-dimensional ordered macroporous (3DOM) gold film modified electrodes using lactate oxidase (LOx) as a case study, within the framework of developing approaches of broad applicability. The electrode was electrochemically fabricated with an inverted opal template, making the surface area of the 3DOM gold electrode up to 18 times higher than that of bare flat gold electrodes. These new electrochemical transducers were characterized by using Field Emission Scanning Electron Microscopy (FE-SEM), Atomic Force Microscopy (AFM) and the X-ray diffraction (XRD). The biosensor was developed by immobilization of lactate oxidase (LOx), on a 3DOM gold electrode modified with a self-assembled monolayer of dithiobis-N-succinimidyl propionate (DTSP). The resulting lactate oxidase biosensor was characterized by electrochemical impedance spectroscopy (EIS). The 3DOM gold electrode not only provides a good biocompatible microenvironment but also promotes the increase of conductivity and stability. Thus, the developed lactate oxidase bioanalytical platforms showed higher mediated bioelectrocatalytic activity compared to others previously described based on polycrystalline gold transducers. The response to varying lactate concentrations has been obtained in the presence of hydroxymethylferrocene as redox mediator in solution. Under these conditions, the bioanalytical platform response for DTSP covalently bound enzyme was improved with respect to that obtained in absence of DTSP.

Ferric Heme-Nitrosyl Complexes: Kinetically Robust or Unstable Intermediates?

We have determined a convenient method for the bulk synthesis of high-purity ferric heme-nitrosyl complexes ({FeNO}6 in the Enemark-Feltham notation); this method is based on the chemical or electrochemical oxidation of corresponding {FeNO}7 precursors. We used this method to obtain the five- and six-coordinate complexes [Fe(TPP)(NO)]+ (TPP2- = tetraphenylporphyrin dianion) and [Fe(TPP)(NO)(MI)]+ (MI = 1-methylimidazole) and demonstrate that these complexes are stable in solution in the absence of excess NO gas. This is in stark contrast to the often-cited instability of such {FeNO}6 model complexes in the literature, which is likely due to the common presence of halide impurities (although other impurities could certainly also play a role). This is avoided in our approach for the synthesis of {FeNO}6 complexes via oxidation of pure {FeNO}7 precursors. On the basis of these results, {FeNO}6 complexes in proteins do not show an increased stability toward NO loss compared to model complexes. We also prepared the halide-coordinated complexes [Fe(TPP)(NO)(X)] (X = Cl-, Br-), which correspond to the elusive, key reactive intermediate in the so-called autoreduction reaction, which is frequently used to prepare {FeNO}7 complexes from ferric precursors. All of the complexes were characterized using X-ray crystallography, UV-vis, IR, and nuclear resonance vibrational spectroscopy (NRVS). On the basis of the vibrational data, further insight into the electronic structure of these {FeNO}6 complexes, in particular with respect to the role of the axial ligand trans to NO, is obtained.

Homotrimetallic oxazolo-ferrocene complexes displaying tunable cooperative interactions between metal centers and redox-switchable character

A synthetic procedure based on the aza-Wittig reaction of alpha-azidoacetyl ferrocene or 1,1?-bis(alpha-azidoacetyl)ferrocene with mono-, di-, and triacyl chlorides and triphenylphosphine has been developed to prepare the new homotrimetallic ferrocene complexes 6, 9, and 10 containing at least two oxazole rings in the conjugation chain. Complexes 9 and 10 exhibited three and two reversible redox processes, respectively, indicating significant electrostatic interaction between the iron centers in these complexes. Protonation properties of complexes 9-13 have been assessed by use of 1H NMR and cyclic voltammetry measurements.

Non-invasive breast cancer diagnosis through electrochemical biosensing at different molecular levels

The rapid and accurate determination of specific circulating biomarkers at different molecular levels with non- or minimally invasive methods constitutes a major challenge to improve the breast cancer outcomes and life quality of patients. In this field, electrochemical biosensors have demonstrated to be promising alternatives against more complex conventional strategies to perform fast, accurate and on-site determination of circulating biomarkers at low concentrations in minimally treated body fluids. In this article, after discussing briefly the relevance and current challenges associated with the determination of breast cancer circulating biomarkers, an updated overview of the electrochemical affinity biosensing strategies emerged in the last 5 years for this purpose is provided highlighting the great potentiality of these methodologies. After critically discussing the most interesting features of the electrochemical strategies reported so far for the single or multiplexed determination of such biomarkers with demonstrated applicability in liquid biopsy analysis, existing challenges still to be addressed and future directions in this field will be pointed out.

Synthesis and electrochemical behavior of the ferrocenyl units assembled on imidoalane and carbaalane clusters

Hydroalumination reaction was effectively carried out on ferrocenylnitrile in the synthesis of imidoalane cluster [HAlNCH2C5H 4FeCp]6 (3). Compound 3 exhibits a reversible electrochemical behavior. In the presence of ferrocenylmethanol, meta thesis reactions were carried out on [HAlNCH2(C4H 3S)]6 (4) and [HAlNCH2Ph]6 (5) in the synthesis of [CpFeC5H4CH2OAlNCH 2(C4H3S)]6 (6) and [CpFeC 5H4CH2OAlNCH2Ph]6 (7). The ferrocenylmethoxide groups present in these two compounds show a single reversible oxidation wave, which suggests their electrochemical equivalence. Electrochemical studies were also carried out on the carbaalane [(AlH) 2(FcCCAl)4(AlNMe3)2(CCH 2Ph)6] (9), which exhibited a considerably broadened wave with shoulders preceding the main anodic and cathodic peak, and it can be assigned to weak electronic interactions between the individual ferrocenyl sites.

The enhanced electronic communication in ferrocenemethanol molecular cluster based on intermolecular hydrogen-bonding

This work presents an electrochemical study of enhanced electronic communication based on intermolecular hydrogen-bonding in ferrocenemethanol (described as FcCH2OH) molecular clusters. The enhanced electronic communication in FcCH2OH clusters is confirmed and further investigated by differential-pulse voltammetry and cyclic voltammetry. A key finding is that this enhanced electronic communication increases the standard rate constant of the electron transfer process. These results will provide us with a further understanding of the electronic communication within the ferrocenyl derivatives which is based on the intermolecular hydrogen-bonding.

1,1?-Bis(4,2?:6?,4?-terpyridin-4?-yl)ferrocene (1) reacts with ZnCl2 to yield a double-stranded 1D-coordination polymer [{Zn2(1)Cl4}?3CHCl3]n. The 1,1?-functionalized ferrocene core adopts a cisoid-conformation, giving rise to a folded conformation for 1 and a double-stranded 1D-polymer chain. This contrasts with previously reported multi-stranded chains supported by 4,2?:6?,4?-terpyridine ligands in which the multiple-nature of the chain arises from multinuclear metal nodes.

Synthesis and characterization of (CH=CH)3-bridged heterobimetallic ferrocene-ruthenium complexes

The complex Fc(CH=CH)2C?C-TMS (Fc = ferrocenyl) was obtained from Wittig olefination of FcCH2PPh3Br with TMS-C?CCH=CHCHO in THF. The conjugated monometallic diene can be desilylated to give Fc(CH=CH)2C?CH, which reacted with RuHCl(CO)(PPh3)3 to produce Fc(CH=CH)3RuCl(CO) (PPh3)2. Treatment of the latter complex with PMe 3, 4-phenylpyridine (PhPy), 2,6-(Ph2PCH2) 2C5H3N (PMP), and KTp (Tp = hydridotris(pyrazolyl)borate) gave Fc(CH=CH)3RuCl(CO)(PMe 3)3, Fc(CH=CH)3RuCl(CO)(PhPy)(PPh 3)2, Fc(CH= CH)3RuCl(CO)(PMP), and Fc(CH=CH)3RuTp(CO)(PPh3), respectively.
