Some important styles of it, such as the smectic, nematic, cholesteric and fishbone were particularly introduced.

Cholesteric liquid crystalline monomers and side chain terpoly (olefin sulphone)s have been prepared and characterised, and their liquid crystalline properties measured too.

The research on their properties of liquid crystals showed that they were thermotropic cholesteric liquid crystals.

A brief introduction to five main electronic ink technologies including microencapsulated electrophoretic,bichromal twisting ball,cholesteric liquid crystal,electrowetting and electrochromic.

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.
