study, four viologen derivatives, namely, 1,1′-bis(4-(bis(4-bromophenyl)amino)phenyl)-[4,4′-bipyridine]dihexafluorophosphate (DBrPV), 1-benzyl-1′-(4-(bis(4-bromophenyl)amino)phenyl)-[4,4′-bipyridine]dihexafluorophosphate (Bn-BrPV), 1,1′-bis(4-(3,6-dibromo-9H-carbazol-9-yl)phenyl)-[4,4′-bipyridine]dihexafluorophosphate (DBrCV), and 1-benzyl-1′-(4-(3,6-dibromo-9H-carbazol-9-yl)phenyl)-[4,4′-bipyridine]d
在这项研究中,四种紫罗碱衍生物,即 1,1'-双(4-(双(4-溴苯基)氨基)苯基)-[4,4'-联吡啶]二六氟磷酸酯 ( DBrPV )、1-benzyl-1' -(4-(双(4-溴苯基)氨基)苯基)-[4,4'-联吡啶]二六氟磷酸盐( Bn-BrPV ), 1,1'-双(4-(3,6-dibromo-9 H -) carbazol-9-yl)phenyl)-[4,4'-bipyridine]dihexafluorophosphate ( DBrCV ), and 1-benzyl-1'-(4-(3,6-dibromo-9 H -carbazol-9-yl)phenyl )-[4,4'-联吡啶]二六氟磷酸盐 ( Bn-BrCV), 被合成。使用四种紫罗碱衍生物作为活性材料制造电致变色器件 (ECD)。ECD的结构是ITO-PET(或ITO-玻璃)/电致变色活性材料/ITO-PET(或ITO-玻璃)。在施加电压下,柔性和刚性
