Crosslinked Poly(amido-amine)s as Superior Matrices for Chemical Incorporation of Highly Efficient Organic Nonlinear Optical Dyes

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) heterocyle-based dyes as side-chain substituent. 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 matrice makes them a superior alternative to conventional high-T g thermoplastic polymers.
