Controlling Near-Infrared Chromophore Electronic Properties through Metal-Ligand Orbital Alignment

Transition-metal complexes of radical ligands can exhibit low-energy electronic transitions in the near-infrared (NIR) spectral region. NIR band energy and intensity sensitively depend on the degree of electronic coupling of the chromophore. Using the example of open-shell complexes derived from platinum and a 1,4-terphenyldithiophenol, we present a novel approach toward spectroscopically distinct NIR dyes for which the degree of electronic coupling correlates with the relative orientation of radical ligand and metal orbitals. Ligand/metal orbital alignment is modulated by auxiliary phosphine donors and selectively results in electron localized Class II-III or delocalized Class III structures that display distinct NIR transitions at 6500 and 4000 cm-1

MOESSBAUER SPECTROSCOPIC STUDIES ON THE GLASS STATE IN DIETYLFERROCENE

The discontinuous temperature dependence of Moessbauer recoil-free fraction observed in diethylferrocene, reflects the transition from the glass state to the super-cooled liquid state followed by crystallization on heating the sample which was prepared by cooling quickly the liquid sample with liquid nitrogen.On cooling the crystallized diethylferrocene, the temperature dependence was similar to that found monoethylferrocene.

Bioactive 1,1?-unsymmetrical bi-functional ferrocenyl compounds using a novel solvent free one pot multicomponent reaction method

A solvent free synthetic method using rice husk ash (RHA) as solid support has been designed for selective functionalization and preparation of novel 1,1?- unsymmetrically bi-functionalized ferrocenyl compounds. The selectively functionalized intermediate compound, Ferrocenyl-1-acetyl-1?-thiosemicarbazone, has been structurally characterized using single crystal X-ray diffraction technique which revealed distinct inter-molecular hydrogen bonding interactions across the thiosemicarbazone chains. Cytotoxic evaluation of five different unsymmetrically bi-functionalized thiosemicarbazone – hydrazone compounds showed potent activity against human leukemia (THP-1) cell line. The unsymmetrical ferrocenyl compounds also showed strong BSA and DNA binding interactions and reversible redox properties.

Ferrocenyl compound as a multiresponsive calcium chemosensor with remarkable fluorescence properties in CH3CN

We have synthesized a novel disubslituted ferrocenyl compound [Fe(C 5H4CO(CH=CH)2C6H4NEt 2)2] (3) that displays a remarkable fluorescence quantum yield (1.1 ¡Á 10-1) in acetonitrile, and we have studied its capacity for calcium detection in depth using both electrochemical and optical techniques in this medium. The results of our NMR analysis reveal that the ligand-calcium interaction is CO-centered and that an uncommon equilibrium occurs between 3 and calcium triflate, involving five species of different stoichiometries. In contrast, our analysis of the UV-vis absorption data indicates that only three species of different stoichiometries are formed when calcium perchlorate is used with 3. Mass spectrometry measurements provide strong support for the formation of all these different species in solution. In addition, the electrochemical detection of calcium triflate by 3 leads to an irreversible FeII/ FeIII oxidation process with an unusual negative shift (-60 mV) caused by the nBu4NBF4 salt effect on the Ca2+-3 interaction process. Compound 3 can also be an original optical probe to detect calcium perchlorate over a wide range of salt concentration by UV-vis absorption spectroscopy. The most original and intriguing property of compound 3 is that it exhibits an unprecedented “multistep” fluorescence behavior upon addition of this salt.

A nanostructured Fc(COCH3)2 film prepared using silica monolayer colloidal crystal templates and its electrochromic properties

Since oxidation and reduction reactions mainly take place on surfaces, enlarging the specific surface of redox materials is the key to achieving excellent electrochemical performance. In this work, by using silica monolayer colloidal crystal templates (MCCTs), a nanostructured Fc(COCH3)2 film is prepared successfully, and such a nanostructure could exhibit the following unique electrochemical properties: the MCCTs could impede the aggregation tendency of Fc(COCH3)2 and possess high electrochemical activity; Fc(COCH3)2 enlarges the contact area and offers more active sites and faster electronic transmission channels. The structure, optical and electrochemical properties of the nanostructured Fc(COCH3)2 were tested and then compared with those of compact Fc(COCH3)2 films to evaluate the role of the nanoarchitecture. The unique structure design of the Fc(COCH3)2 film enables outstanding performance, showing a large transmittance change (DeltaT) of 37% at 550 nm when switched between 0.5 V and -2.5 V, which is approximately ninefold higher than that of the compact Fc(COCH3)2 film (approximately 4%). Response times of coloration and bleaching are found to be only 16.15 s and 5.56 s. Furthermore, the nanostructured Fc(COCH3)2 film shows much better cycling stability than the compact one. The results indicate that the nanostructure could significantly improve the electrochemical performance of the Fc(COCH3)2 film due to the increase in electrochemical active sites and the enhancement of the “D-to-A” redox switch of ferrocene.

Lanthanide Ion Chelates of Dibenzyl 1,1′-Diacetylferrocenebis(hydrazonatocarbodithioate)

A new ligand, dibenzyl 1,1′-diacetylferrocenebis(hydrazonatocarbodithioate), Fe[C5H4C(CH3)=NNHCSSCH2C6H5)2] (H2Dafhb) and its chelates with lanthanide ions, Ln(Dafhb)Cl (Ln = lanthanide) have been prepared by the reaction of the H2Dafhb with LnCl3. All compounds were characterized by elemental analyses, IR, (1H) NMR, UV, electrolytic conductivity and TGA measurements. It is shown that the ligand coordinates to the metal in the thiol form and that one chloride ion participates in coordination. The chelates are non-electrolytes in DMF and are more thermostable than the ligand due to formation of chelate rings.
