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.

Synthesis of citric-acid-based dendrimers decorated with ferrocenyl groups and investigation of their electroactivity

Fc (ferrocene)-functionalized citric acid dendrimers were successfully synthesized via the reaction of citric acid dendrimers with ferrocene methanol using dicyclohexylcarbodiimide. ClOC?PEG?COCl was used as the core, and the related dendrimers were synthesized divergently. Subsequently, each generation was functionalized with ferrocene methanol. The obtained Fc-dendrimers were characterized by 1H NMR and FTIR spectroscopy. We have studied the relocation of electrons around the peripheries of dendrimers and between their redox terminals and electrodes by studies of the electrochemistry of dendrimers awarding metallocenes as functional?s groups, because these compounds can be stabilized together their oxidized and their reduced states. In addition, the voltammograms of each Fc-functionalized generation were studied and the influence of scan rate, solvent, and [Fe] unit and the concentration of the Fc-dendrimers were investigated.

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.
