Abstract:

2,5-Diphenyl thiophene(DPT),1,4-di-2-thienylbenzene(DTP)and 1,4-di-(3-methyl-2-thienyl)benzene(DMTP)are synthesed by Kumada coupling,and electropolymerized as PDPT,PDTP and PDMTPPDPT is electrochemical unstable,while PDTP and PDMTP have well electroactivity between 0—1.2 VBesides,PDTP and PDMTP display cyan-orange and red-green-blue electrochromism respectively,which could be used in electrochromic devices.

摘要:

利用Kumada偶联合成了2,5-二苯基噻吩(DPT)、1,4-二噻吩基苯(DTP)及1,4-二(3-甲基-2-噻吩基)苯(DMTP),并电聚合得到相应的聚合物PDPT、PDTP和PDMTP。PDPT的电化学稳定性较差,而PDTP和PDMTP在0~1.2 V间具有良好的电活性。此外,PDTP和PDMTP分别具有青-橙和红-绿-蓝的电致变色现象,可用于电致变色器件。
