摘要：
The present invention relates to nonlinear optical material comprising nonlinear optical dihydroxy arylhydrazones and to nonlinear optical materials comprising compositions containing at least one divalent moiety of nonlinear optical arylhydrazones. The present invention also relates to polyesters, polyestercarbonates, polycarbonates, polyethers, and poly(hydroxy ether) polymers, incorporating the dihydroxy arylhydrazone as recurring divalent moieties in the backbone of the polymer. The polymeric compositions of the present invention have high glass transition temperatures and exhibit stable nonlinear optical activity at high temperatures over a period of time.
