通过 Horner-Wadsworth-Emmons 聚合合成了一系列基于缺电子苯并双噻唑和富电子芴部分的亚乙烯基连接共聚物。制备了三种不同的聚合物P1、P2和P3，分别带有辛基、3,7-二甲基辛基和2-(2-乙氧基)乙氧基乙基侧链。这些聚合物均具有适中的分子量、在非质子有机溶剂中良好的溶解性以及在稀溶液中高的荧光量子效率。 P2带有支化的3,7-二甲基辛基侧链，比其他聚合物表现出更好的溶解度，但也表现出所有聚合物中最低的热分解温度。总体而言，侧链对溶液中聚合物光学性质的影响可以忽略不计，因为所有三种聚合物在溶液和薄膜中都具有相似的吸收和发射光谱。在聚（N-乙烯基咔唑）主体中使用聚合物的稀释混合物的客体-主体发光二极管发出蓝绿色发射，其中P2表现出最高的发光效率，在~500 nm处为0.61 Cd/A。 © 2012 Wiley periodicals, Inc.

A series of vinylene-linked copolymers based on electron-deficient benzobisthiazole and electron-rich fluorene moieties were synthesized via Horner–Wadsworth–Emmons polymerization. Three different polymers P1, P2, and P3, were prepared bearing octyl, 3,7-dimethyloctyl, and 2-(2-ethoxy)ethoxyethyl side chains, respectively. The polymers all possessed moderate molecular weights, good solubility in aprotic organic solvents, and high fluorescence quantum efficiencies in dilute solutions. P2, which bore branched 3,7-dimethyloctyl side chains, exhibited better solubility than the other polymers, but also exhibited the lowest thermal decomposition temperature of all polymers. Overall, the impact of the side chains on the polymers optical properties in solution was negligible as all three polymers gave similar absorption and emission spectra in both solution and film. Guest-host light-emitting diodes using dilute blends of the polymers in a poly(N-vinylcarbazole) host gave blue-green emission with P2 exhibiting the highest luminous efficiency, 0.61 Cd/A at ~500 nm. © 2012 Wiley Periodicals, Inc.
