Direct Chemical Modification of pi-Conjugated Polymers and their Electronic Properties

研究了π共轭聚合物上咔唑骨架在2，7位上的直接Friedel-Crafts酰化反应。在优化的反应条件下，咔唑单元的3，6位酰化反应成功进行。在此基础上，采用酰化法合成了新型π共轭聚合物，并通过直接化学修饰的方法，研究了新型π共轭聚合物的结构单元，以实现对π共轭聚合物电子态的控制。因此，羰基单元和苯胺衍生物之间的脱水反应可以用作直接聚合物官能化方法。

Direct Friedel-Crafts acylation to the carbazole backbone on pi-conjugated polymer connecting at its 2,7-position was investigated. The acylation at 3,6-position of carbazole unit successfully occurred under the optimized reaction condition. Furthermore, novel pi-conjugated polymer for organic photovoltaic devices was synthesized by using the acylation method.At the same time, new building blocks were investigated in order to achieve the control of the electronic state via direct chemical modification. As a result, the dehydration reaction between carbonyl unit and aniline derivative can be applied as a direct polymer functionalization method.
