摘要

Abstract: A new type of liquid crystalline side chain polysiloxane has been built through self- assembly via intermolecular hydrogen bonding between H-bond donor and acceptor moieties. Poly (methylsi1oxanes) and poly (methy1-co-dimethylsiloxanes) with side chains containing 4-alkoxybenzoic acid pendant groups attached through aliphatic spacers were synthesized for use as H-bond donor polymers. trans-4-[(4-Methoxybenzoyl) oxy]-4'- ...
