Electrochemical and Thermal Properties of Ferrocenyl 1,2,3-Triazole

Ferrocenyl 1,2,3-triazoles with nitro (3a similar to 3c) or amino (4a similar to 4c) were synthesized and characterized. The cyclic voltammogram investigations revealed that redox-active ferrocenyl groups of two series of compounds exhibited quasireversible one-electron transfer processes. As compared to compound 3b, the potential for 4b with amino cathodically shifted 17 mV thereby suggesting easier oxidation by loss of an electron for the latter. Their thermal behaviors indicated that compounds 3a similar to 3c were all non-mesomorphic, and showed crystal polymorphic phase transitions in the heating and cooling cycles. Whereas 4a similar to 4c displayed liquid crystal behaviors over 90 degrees C mesophase range. The research is supposed to provide some theoretical basis for this kind of compound using in function materials.
