Crosslinked poly(amido-amine)s as superior matrices for chemical incorporation of highly efficient organic nonlinear optical dyes

Abstract

We report on the synthesis and characterization of new crosslinked polymeric matrices, pertaining to the class of poly(amido-amine)s (PAAs), functionalized with highly performing nonlinear optical (NLO) heterocycle-based dyes as side-chain substituents. Linear, soluble, and highly crosslinked NLO-functionalized PAA networks can be easily prepared under mild conditions. The wide-ranging tunability of optical and mechanical properties of these matrices makes them a superior alternative to conventional high-Tg thermoplastic polymers.
