报道了一种通用的合成共轭主族元素基聚合物的一般合成路线。这些聚合物含有基于S，Se和Te的五元硫族化合物环，并且我们证明了可以通过受控原子取代化学容易地调节光电性质。此外，区域规则的混合噻吩硒碲吩和硒芴共聚物的合成，以提供所提出的金属乳酸盐转移/交叉偶联聚合方法的范围的进一步说明。
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.
