通过准轮烷与液晶单体的烯硫醇共聚反应，合成了主链型液晶聚轮烷。利用差示扫描量热法研究了轮烷结构及其含量对液晶性能的影响。在LC聚合物上引入轮烷部分降低了LC相的稳定性。轮烷部分的中和也使LC相不稳定，最可能是由于轴LC聚合物链上的轮烷的可移动轮组分。
Main chain-type liquid crystalline (LC) polyrotaxanes were synthesized via the ene-thiol copolymerization of pseudorotaxane and LC monomers. The effects of the rotaxane moiety and its content on the LC properties were investigated using differential scanning calorimetry. Introduction of the rotaxane moiety on the LC polymer reduced the stabilization of the LC phase. Neutralization of the rotaxane moiety also destabilized the LC phase, most likely due to the movable wheel components of the rotaxane on the axle LC polymer chain.
