10.3. Synthesis and characterization of azo type crown ether liquid crystalUsing cis(trans)-diaminodibenzo-14-crown-4 and cis(trans)-diaminodibenzo-18-crown-6 as raw materials, a new kind of azo type crown ether liquid crystal was synthesized through diazotization and coupling reactions on the base of molecular design, which can be divided into four series, sixteen compounds according to the end alkoxy group, crown ether ring and configuration of the compound.
