合成并表征了含有硝基(3a～3c)和氨基(4a～4c)的两系列二茂铁1,2,3-三唑化合物. 循环伏安实验中代表化合物3b与4b均展示准可逆的单电子氧化还原进程, 且相对于3b, 化合物4b的氧化还原电位向阴极方向移动17 mV左右, 说明含有氨基的4b更易于氧化. 热性质研究表明, 含有硝基的系列化合物在升温或降温过程中发生了多晶相转变; 而含有氨基的系列化合物随着烷基链的延长, 出现了晶体到介晶相的转变过程, 且介晶相温度范围可宽达90 ℃. 这些研究为此类化合物在功能材料方面的应用提供一定的理论依据.

Ferrocenyl 1,2,3-triazoles with nitro (3a～3c) or amino (4a～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～3c were all non-mesomorphic, and showed crystal polymorphic phase transitions in the heating and cooling cycles. Whereas 4a～4c displayed liquid crystal behaviors over 90 ℃ mesophase range. The research is supposed to provide some theoretical basis for this kind of compound using in function materials.
