Novel optically active π-conjugated polymers having a chiral bifacial indacenodithiophene backbone were synthesized by Suzuki-Miyaura cross coupling polymerization with benzothiadiazole comonomer. The obtained -chiral polymers form amorphous thin films on HOPG and exhibit good chirality-induced spin selectivity with spin polarization of nearly 70%.
通过与苯并噻二唑共聚单体进行铃木-宫浦交叉偶联聚合反应，合成了具有手性双界面茚并二噻吩主链的新型光学活性π共轭聚合物。所得到的手性聚合物在高定向热解石墨上形成非晶薄膜，并表现出良好的手性诱导自旋选择性，自旋极化率接近70%。
