Synthesis, characterization, and electrochemical properties of ferrocenylimidazolium

A series of ferrocene-based methylimidazolium receptors were prepared and their electrochemical properties of sensing the various anions, the dependence of alkyl chain length, were investigated by voltammetry technologies. All of these ferrocenylimidazolium compounds were fully characterized by elemental analysis, NMR and mass spectrometry. Moreover, the structures of ferrocene-based methylimidazolium receptors 1a, 1b, 2b, and 3b were confirmed by X-ray crystallography. The ferrocenylimidazolium 1a and 2a receptors in which the ferrocene center and methylimidazolium fragments are directly linked showed redox waves for both the ferrocenyl moiety and the methylimidazolium moiety and exhibited rather strong electrochemical sensing properties for F- anion.

Long-range electronic connection in picket-fence like ferrocene-porphyrin derivatives

The effects of a direct connection between ferrocene and porphyrin units have been thoroughly investigated by electrochemical and spectroscopic methods. These data not only reveal that substitution of the porphyrin macrocycle by one, two, three or four ferrocenyl groups strongly affects the electronic properties of the porphyrin and ferrocenyl moieties, they also clearly demonstrate that the metallocene centres are “connected” through the porphyrin-based electronic network. The dynamic properties of selected ferrocene-porphyrin conjugates have been investigated by VT NMR and metadynamic calculations. 1,3-Dithiolanyl protecting groups have been introduced on the upper rings of the ferrocene fragments to allow a straightforward and easy access to redox active picket-fence porphyrins. X-ray diffraction analyses of the zinc(ii) 5-[1?-[2-(1,3-dithiolanyl)]ferrocenyl]-10,15,20-tri(p-tolyl)porphyrin and 5,15-bis[1?-[2-(1,3-dithiolanyl)]ferrocenyl]-10,20-bis(p-tolyl)porphyrin complexes reveal the existence of S-Zn bonds involved in supramolecular arrays. The solid state analysis of the trans-5,15-di-(1?-(formyl)ferrocenyl)-10, 20-di-(p-tolyl)-porphyrinatozinc(ii) complex, obtained by deprotection of the dithiolane substituted analog, is conversely found in the crystal lattice as a monomer exhibiting a hexacoordinated zinc metal centre.

Electrical current oscillations in vapor-adsorbed ferrocene derivatives having two substituted groups

Oscillations in electrical current as a function of time have been observed in a specific temperature range in the samples of 1,1?-diacetylferrocene and 1,1?-ferrocenedicarboxylic acid with adsorbed ethanol vapor in a sandwich-type cell. The frequency of current oscillations has been found to decrease with bias voltage and sample temperature and to increase with vapor pressure. The frequency of current oscillations for the mono-group substituted derivatives is higher than the corresponding frequency for the derivatives having two substituted groups. Again, the frequency of oscillations for -COCH3 group substituted derivatives is higher than the corresponding value for -COOH group substituted derivatives. The observation of current oscillations is possibly associated with some kind of time dependent phase changes, arising from the structural nonrigidity of the molecules, in the solid-ethanol vapor system at the sample surface layer. The “ball-bearing” motion of the cyclopentadienyl rings of ferrocene unit, nature and number of substituted groups, cooperative interaction of the neighboring molecules influence the structural nonrigidity and hence the oscillatory behavior of current. Reasons are given for ruling out other models of current oscillations in semiconductors.

Bis [1,1?-N,N?-(2-picolyl)aminomethyl] ferrocene as a redox sensor for transition metal ions

The compound bis[1,1?-N,N?-(2-picolyl)aminomethyl]ferrocene, L1, was synthesized. The protonation constants of this ligand and the stability constants of its complexes with Ni2+, Cu2+, Zn2+, Cd2+ and Pb2+ were determined in aqueous solution by potentiometric methods at 25C and at ionic strength 0.10 mol dm-3 in KNO3. The compound L1 forms only 1:1 (M:L) complexes with Pb2+ and Cd2+ while with Ni 2+ and Cu2+ species of 2:1 ratio were also found. The complexing behaviour of L1 is regulated by the constraint imposed by the ferrocene in its backbone, leading to lower values of stability constants for complexes of the divalent first row transition metals when compared with related ligands. However, the differences in stability are smaller for the larger metal ions. The structure of the copper complex with L1 was determined by single-crystal X-ray diffraction and shows that a species of 2:2 ratio is formed. The two copper centres display distorted octahedral geometries and are linked through the two L’ bridges at a long distance of 8.781(10) A. The electrochemical behaviour of L1 was studied in the presence of Ni2+, Cu2+, Zn2+, Cd2+ and Pb2+, showing that upon complexation the ferrocene – ferrocenium half-wave potential shifts anodically in relation to that of the free ligand. The maximum electrochemical shift (DeltaE1/2) of 268 mV was found in the presence of Pb2+ followed by Cu2+ (218 mV), Ni 2+ (152 mV), Zn2- (111 mV) and Cd2+ (110 mV). Moreover, L1 is able to electrochemically and selectively sense Cu2+ in the presence of a large excess of the other transition metal cations studied.

Label-Free Homogeneous Electrochemical Sensing Platform for Protein Kinase Assay Based on Carboxypeptidase Y-Assisted Peptide Cleavage and Vertically Ordered Mesoporous Silica Films

Presented herein is a simple, robust, and label-free homogeneous electrochemical sensing platform constructed for the detection of protein kinase activity and inhibition by integration of carboxypeptidase Y (CPY)-assisted peptide cleavage reaction and vertically ordered mesoporous silica films (MSFs). In this sensing platform, the substrate peptide composed of kinase-specific recognized sequence and multiple positively charged arginine (R) residues was ingeniously designed. In the presence of protein kinase, the substrate peptide was phosphorylated and then immediately resisted CPY cleavage. The phosphorylated peptide could be effectively adsorbed on the negatively charged surface of MSFs modified indium-tin oxide (ITO) electrode (MSFs/ITO) by noncovalent electrostatic attraction. The adsorbed peptide was subsequently used as a hamper to prevent the diffusion of electroactive probe (FcMeOH) to the electrode surface through the vertically aligned nanopores, resulting in a detectable reduction of electrochemical signal. As demonstrated for the feasibility and universality of the sensing platform, both protein kinase A (PKA) and casein kinase II (CK2) were selected as the models, and the detection limits were determined to be 0.083 and 0.095 UmL-1, respectively. This sensing platform had the merits of simplicity, easy manipulation, and improved phosphorylation and cleavage efficiency, which benefited from homogeneous solution reactions without sophisticated modification or immobilization procedures. In addition, given the key role of inhibition and protein kinase activity detection in cell lysates, this proposed sensing platform showed great potential in kinase-related bioanalysis and clinical biomedicine.
