Donor-Embedded Nonlinear Optical Side Chain Polyimides Containing No Flexible Tether: Materials of Exceptional Thermal Stability for Electrooptic Applications

Abstract

We describe here the preparation and characterization of the first processible nonlinear optical (NLO) polyimide where the chromophore is not incorporated using a flexible tether functionality. The polymer has a very high glass temperature and shows exceptional thermal and chemical stability. Poled samples also show outstanding orientational stability, consistent in part with the high glass transition temperature. © 1995, American Chemical Society. All rights reserved.
