Synthesis and Optical Properties of Conjugated Poly(aromatic diacetylenes);

Theoretical Investigation of the Topochemical Polymerization of Diacetylenes in Solid Phase and the Side-group Effect on the Reactions;

Novel conjugated polymer containing diacetylenes was synthesized by CuCl-catalyzed oxidative coupling of aromatic diynes.

Synthesis and Property of Liquid Crystal Compounds:trans-Cyclohexyltolan-type with Lateral Fluorines;

Six lateral difluorine substituted tolan-type liquid crystals were synthesized via Sonogashira cross-coupling of 4-alkylphenylacetylene and 4-iodo-2,3-difluoro-1-alkoxybenzene under the protection of argon.

Preparation and application of nonlinear optical material polydiacetylene derivatives and its application;

The Third-order Nonlinear Optical Properties for Substituted Diphen ylpol yene and Su bstituted Polydiacetylene;

This paper reviewed the recent years' progress of studies on third order non - linear optics in the field of conjugated polymers, including polydiacetylene, conductive polymers such as polyacetylene or polythiophene and rigid heterocyclic ladder polymers, and predicted their potential prospects of applications.
