Abstract

In the present article we report about the synthesis, quantum chemical model calculations and non-linear optical characterisation of a novel polyurethane based polymer — a bipolar organic compound N-(indan-1,3-dion-2-yl)-4- N′, N′-dialkyaminopyridinium betaine (IPB) containing charged electron donor and electron acceptor groups covalently bonded to polyurethane polymer backbone. This newly synthesised IPB containing polymer can be regarded as a promising thermally stable organic non-linear optical material with a long time performance for photonics applications.
