donor-acceptor (DA) alkylbithiophene derivatives of oxadiazole, thiadiazole and triazole is reported. Taking advantage of the Fiesselmann reaction, reactive bithiophene synthons having alkyl or alkoxy substituents at designated positions are prepared. Following a synthetic strategy, featuring the bottom-up approach, sequential structural elements are built, starting from a simple thiophene compound, until the target
报道了一种用于制备恶二唑、噻二唑和三唑的官能化、可溶性、供体-受体 (DA) 烷基联噻吩衍生物的新合成方法。利用 Fiesselmann 反应,制备在指定位置具有烷基或烷氧基取代基的反应性联噻吩合成子。遵循以自下而上的方法为特色的合成策略,从简单的噻吩化合物开始,直到获得目标分子,都以良好的收率构建了连续的结构元素。作为对恶二唑和噻二唑合成方法的补充,提出了提供 4H-1,2,4-三唑单元的有效闭环反应。所有目标双极性化合物都显示出强光致发光,测得的量子产率高达 0.59。
