Abstract: A variety of thermally stable NLO chromophores have been attached via a short tethers to 3,5-diaminophenol to produce NLO substituted aromatic diamine monomers suitable for polyimide formation. This may be accomplished either via nucleophilic displacement or by Mitsunobu coupling for base-sensitive materials. The functionalized diamines have been incorporated into a variety of polyimide materials yielding thermally stable polymers with Tg's ranging from 210-230 degrees C. These materials may be poled at or near the polymer glass temperature and the polar alignment thus induced was stable for long periods at 100 degrees C. The improved thermal stability of the chromophores containing diarylamino donor substitution was also manifested in the cured polymers and is also apparently not significantly jeopardized by the inclusion of an alkyl tether.
