In this dissertation, the efforts were focused on design and synthesis of chiral tmsymmetrical urea, cholic acid and heteroaromatic molecular tweezers and their molecular recognition as well as enantioselective recognition.

In this dissertation, the efforts were focused on design and synthesis of new types of chiral and achiral azoamide hosts,bowl-shaped steroid cholic acid methyl esters with one chiral arm under microwave irradiation and heteroaromatic molecular tweezers under microwave irradiation in solid state and their molecular recognition as well as enantioselective recognition.

Recent advances in design and preparation of functional polymers based on steroid cholic acid are reviewed with focus on side group type of polymeric steroid cholic acid.

This paper reviews the recent progress in molecular recognition of artificial receptors derived from steroid cholic acid as one of the structural components.

Progress on the synthesis of cholesterol esters is summarized.

Two types of samples for cholesteryl derivative,coattail-like cholesterol ester and cholesteryl dicarboxylate,were synthesized by using a super esterification method and a catalytic acylation method.

In the case of strongly boundary anchoring and the polymer dispersed cholesteric liquid crystals(PDCLC),the effect of electric field on the frustrated cholesteric liquid crystals with negative dielectric anisotropy were summarized.

Effects of concentration and boundary conditions on cholesteric liquid crystalline condensed state structure and optical property of ethyl-cyanoethyl cellulose were investigated.
