Investigation of Triphenylamine–Thiophene–Azomethine Derivatives: Toward Understanding Their Electrochromic Behavior

摘要: A series of thiophenoazomethines connected to a central triphenylamine were prepared. The effect the type aminothiophene used prepare conjugated azomethines and number azomethine bonds, ranging from one three, flanking on spectral, electrochemical, spectroelectrochemical properties investigated. Both absorption fluorescence (6–8) derived 2,5-diaminothiophene (1) found be contingent azomethines. spectral red-shifted with increasing bonds. In contrast, (9–11) 2-aminothiophene (2) not perturbed by However, their relative counterparts 1. oxidation potentials also structure. They shifted more positive potent...
