Abstract

An NLO-functionalized polyurethane with a highly nonlinear heteroaromatic thiophene chromophore having a tricyanovinyl group was synthesized and characterized. Heteroaromatics such as thiophene are expected to exhibit high nonlinear activity due to the lower delocalization energy relative to the benzene derivatives. It showed high second-order nonlinearity with a SHG coefficient, d₃₃=51 pm/V. In addition, the high thermal stability of the aligned dipoles was observed up to 150°C without any measurable decay. This good stability was originated from the polymer backbone rigidity caused by the effective inter-chain hydrogen bridges between neighboring the polyurethane chains.
