4“‐ethylenedioxythineyl)‐2′‐thienyl]benzene) (P3ETB), was also prepared. The electrochemical and electrochromic properties of these conjugated oligomers and polymer were investigated. These oligomer and polymer films showed reversible, clear color changes upon electrochemical doping and dedoping. The color of the P3ETB film reversibly changed from orange to blue under doping and dedoping. The switching times
一系列星形共轭低聚物,1,3,5-三(2'-噻吩基)苯(3TB),1,3,5-三(3',4'-乙撑二氧噻吩基)苯(3EB),1, 3,5-三[5',2”-(3“,4”-乙二氧基-噻吩基)-2'-噻吩基]苯(3ETB)和1,3,5-三[5',2”-(合成了3“,4”-乙二氧基噻吩基] -2'-噻吩基] -4-(3',4'-乙二氧基噻吩基)苯(3TB-4EDOT)。还制备了星形聚合物聚(1,3,5-三[5',2”-(3“,4”-乙撑二氧噻吩基)-2'-噻吩基]苯)(P3ETB)。研究了这些共轭低聚物和聚合物的电化学和电致变色性质。这些低聚物和聚合物膜在电化学掺杂和去掺杂时显示出可逆的,清晰的颜色变化。在掺杂和去掺杂下,P3ETB膜的颜色可逆地从橙色变为蓝色。掺杂和去掺杂的切换时间分别为1.2和0.9 s。
