摘要
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.
