以手性联二萘(BINOL)取代的2, 3-二氟对苯二腈和3, 3'-联咔唑为单体，通过碳-氮偶联反应得到一对共轭聚合物(R)-P1和(S)-P1，并且通过1H NMR与13C NMR、凝胶渗透色谱(GPC)、热重分析(TGA)、荧光发射光谱(PL)、圆二色谱(CD)和圆偏振发光(CPL)光谱等对聚合物的化学结构、分子量、热稳定性以及光物理性质等进行了表征.结果表明:该聚合物具有明显的聚集诱导发光(AIE)性质；手性联二萘侧基能有效地诱导共轭主链的微环境，使该聚合物具有手性活性，且表现出CPL特性.

Synthesis,Aggregation-Induced Emission and Circularly Polarized Luminescence of Poly(3, 3'-bicarbazolylterephthalonitrile) with Chiral Binaphthalene Pendant Groups

A couple of conjugated polymers (R)-P1 and (S)-P1 were synthesized using chiral Binaphthalene (BINOL) substituted 2, 3-tetrafluoroterephthalonitrile and 3, 3'-bicarbazole as the monomers via C-N coupling reaction. The chemical structures and properties of the polymers were characterized with 1H NMR, 13C NMR, gel permeation chromatography (GPC), thermogravimetric analysis (TGA) as well as PL spectra, circular dichroism(CD) and circularly polarized luminescence (CPL) spectra. The experimental results suggested that the obtained polymers were aggregation-induced emission (AIE) and CPL active, manifesting the chirality transmission from 1, 1'-binaphthalenependant groups to the conjugated main chain.
