采用Suzuki反应合成了9,9-二辛基芴(DOF)与2-噻吩基苯并噻二唑(DBT)的共聚物,并分别用N-己基咔唑和苯封端,分别简称为PDOF-DBT-Cz和PDOF-DBT-B。研究了共聚物的物理、电化学和热性能。结果表明,N-己基咔唑取代PDOF-DBT的封端基团,可以改变其发光颜色,提高发光效率。
Copolymers of 9,9-dioctylfluorene (DOF) and 2-thienyl-benzothiadiazole (DBT) were synthesized by Suzuki reaction and end-capped by N-hexyl-carbazole and benzene, which were abbreviated as PDOF-DBT-Cz and PDOF-DBT-B, respectively. The photophysical, electrochemical and thermal properties of the copolymers were studied. The results indicated that replacement of N-hexyl-carbazole as end-capping group of PDOF-DBT can vary light color and improve luminescence efficiency.
