Abstract
The present invention relates to nonlinear optical materials comprising aminoaryl hydrazones and to nonlinear optical polymeric compositions containing recurring covalently bonded moieties derived from the aminoaryl hydrazones of the invention. 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.
