Two novel alternating phenylenevinylene copolymers and as well as one fluorenevinylene copolymer connected at the 1,7 bay positions with perylene bisimide were synthesized by Heck coupling. They were characterized by GPC, FT-IR, H NMR, TGA, TMA, UV–vis, cyclic voltammetry and photoluminescence (PL) emission spectra. The copolymers were soluble in common organic solvents and thermally stable up to ∼300°C
通过 Heck 偶联合成了两种新型交替亚苯基亚乙烯基共聚物以及一种在 1,7 湾位置与苝双酰亚胺连接的芴亚乙烯基共聚物。通过 GPC、FT-IR、H NMR、TGA、TMA、UV-vis、循环伏安法和光致发光 (PL) 发射光谱对它们进行了表征。该共聚物可溶于常见的有机溶剂,并且热稳定性高达~300°C。它们的玻璃化转变温度为 48–60°C。长波长吸收最大值位于 510–542nm,光学带隙为 ∼2.0eV。和 的 PL 发射最大值相对于 发生红移。 、 的光伏性能也得到了研究。
