NLO polymers containing as active chromophore in dandionyl-pyridinium, betaine units: synthesis, modeling and characterization

摘要

In present article we report about synthesis, quantum chemical model calculations, non-linear optical characterization and dependencies of hte surface potential changes on irradiation with light of novel polyurethane based polymers, namely a bipolar organic compound N-(indan-1,3-dion-2-yl)-4-N',N'-dialkylaminopyridinium betaine (IPB) containing charged electron donor and electron acceptor groups covalently bonded to polyurethane polymer backbone. These newly synthesized IPB containing polymers could be regarded as a promising thermally stable organic non-linear optical materials with long time performance for photonic applications.
