Diacetylenes for advanced Materials.

Abstract:

Diacetylenes are known as unique monomers that undergo solid-state polymerization to give materials for third order nonlinear optical applications. However, because of their highly crystalline nature, their applications are limited due to difficulty in process to thin films. On the other hand, diacetylenes are compounds which exhibit many interesting reactions, and there exist various potential applications as materials for advanced technology. The polymers which contain diacetylene groups in main or side chains, can easily be synthesized by the oxidative coupling reactions. It was found recently that some polymers having polar dyes exhibited extremely large and stable second order nonlinear optical coefficients, and they were attributed to their stable polymer chain conformation.

In this lecture, some unique reactions of diacetylene are reviewed, and various diacetylene-containing polymers for nonlinear optical applications, are presented.
