Organic and polymeric materials have emerged in recent years as candidates
for advanced device and systems applications. This interest has arisen from
the promise of extraordinary optical, structural, and mechanical properties
of certain organic materials, and from the fundamental success of molecular
design performed to create new materials.
Our approach to the problem is to develop an understanding of the molecular
basis of non-linear optical activity, incorporate the most promising
candidates into tractable polymers, and evaluate these materials in device
format. This paper will review some of the recent developments in the NLO
materials effort at Hoechst Celanese.
