综述了目前在手性向列相液晶（N*-LC）场中采用化学聚合或电化学聚合方法合成π共轭聚合物的研究进展。以下是π共轭聚合物领域中值得注意的进展。(1)在N*-LC场中采用不对称界面聚合法制备了螺旋聚乙炔（H-PA）的螺旋脂肪族共轭聚合物。（ii）在N*-LC场中采用不对称电化学聚合的方法合成了具有电活性的螺旋芳香共轭聚合物聚（3,4-乙烯二氧噻吩）（PEDOT）和聚二氧噻吩（PBT）。（iii）在N*-LC场中采用不对称Stille缩聚反应合成了手性芳香共轭共聚物，如聚二乙烯-苯基（PBTP）衍生物。全文强调，利用N*-LC体系作为不对称聚合场，可以使侧链上不含手性取代基的脂肪族和芳族π共轭聚合物形成螺旋。
This review presents the progress made on current research in the synthesis of π-conjugated polymers in chiral nematic liquid crystal (N*-LC) fields through either chemical or electrochemical polymerization. The following are noteworthy advances in the field of π-conjugated polymers. (i) Helical aliphatic conjugated polymers of helical polyacetylene (H-PA) were synthesized using asymmetric interfacial polymerization in N*-LC fields. (ii) Helical aromatic conjugated polymers with electroactive properties, such as poly(3,4-ethylenedioxythiophene) (PEDOT) and polybithiophene (PBT), were synthesized using asymmetric electrochemical polymerization in N*-LC fields. (iii) Chiral aromatic conjugated copolymers, such as the poly(bithienylene-phenylene) (PBTP) derivative, were synthesized using the asymmetric Stille polycondensation reaction in N*-LC fields. Throughout the document, it has been emphasized that by using N*-LC systems as asymmetric polymerization fields, helix formation is possible for aliphatic and aromatic π-conjugated polymers without chiroptical substituents on the side chains.
