A versatile and general synthetic route for the synthesis of conjugated main group element-based polymers, previously inaccessible by conventional means, is reported. These polymers contain five-membered chalcogenophene rings based on S, Se, and Te, and we demonstrate that optoelectronic properties can be readily tuned via controlled atom substitution chemistry. In addition, regioregular hybrid thiophene-selenophene-tellurophene and selenophene-fluorene copolymers were synthesized to provide a further illustration of the scope of the presented metallacycle transfer/cross-coupling polymerization method.
报道了一种以前无法通过常规手段获得的用于合成基于主族元素的共轭聚合物的多功能通用合成路线。这些聚合物含有基于 S、Se 和 Te 的五元杂环并苯环,我们证明通过受控原子取代化学可以很容易地调节光电性能。此外,还合成了具有规正的杂噻吩-硒吩-碲吩和硒吩-芴共聚物,进一步说明了所提出的金属环转移/交叉偶联聚合方法的适用范围。
