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.
