The 2H-benzotriazolyl group is introduced as a new electron-withdrawing group for NLO-active chromophores. Novel benzotriazole derivatives and hydrazones have been synthesized. While their electronic structure and acceptor capability is comparable to those of structurally related nitro compounds, 2H-benzotriazoles show a more favorable transparency-nonlinearity trade-off for NLO applications. The first molecular hyperpolarizabilities β have been measured with hyper-Raleigh scattering (HRS).
