キラルスメクチック液晶場でのヘリカルネットワークポリマーの合成とその円偏光発光特性の評価

Chiral liquid crystals can be applied to asymmetric polymerization solvents to synthesis helical polymers. Synthesis of helical network polymers (HNPs) through photocrosslinking polymerization in chiral nematic liquid crystals (N*-LCs) has been reported. In this work, HNPs were synthesized in chiral smectic liquid crystals (SC*-LCs) as asymmetric medium. This is the first successful asymmetric polymerization using SC*-LCs. The HNPs showed a striated fan-shaped texture attributed to SC*-LCs and exhibited circularly polarized luminescence (CPL). The present HNPs have highly ordered structures compared to the HNPs synthesized in N*-LCs.
