我们提出了四个新的可溶液处理的,含苯并双恶唑和芴基团的荧光聚(亚芳基亚乙烯基)荧光粉的合成。两种不同的部分(顺式和反式-苯并二恶唑)和两个不同的烷基取代基(辛基和3,7-二甲基辛基)用于研究结构对这些聚合物的电子,光学和热学性质的影响。使用紫外可见和荧光光谱,循环伏安法,热重分析(TGA)和差示扫描量热法(DSC)对聚合物进行表征。所有聚合物均具有中等分子量,在非质子有机溶剂中的良好溶解性,在稀溶液中的高荧光量子效率和高电子亲和力。循环伏安法显示这些聚合物的准可逆还原。使用聚合物在聚(N-乙烯基咔唑基体发出蓝光,在约470 nm处的发光效率高达1 Cd / A,这对于发出深蓝光的聚合物LED非常有希望。

We present the synthesis of four new solution-processable, fluorescent poly(arylenevinylene)s containing benzobisoxazole and fluorene moieties. Two different moieties (cis- and trans-benzobisoxazole) and two different alkyl substituents (octyl and 3,7-dimethyloctyl) were used to study the impact of the structure on the electronic, optical, and thermal properties of these polymers. The polymers were
