Chemistry and nonlinear optical properties of new 2H-benzotriazole derivatives
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).

The Preparation and Some Reactions of a Benztriazole Substituted Vinamidium Salt
A three step synthesis of a novel 2-(1-benzotriazolyl)-vinamidium salt is described along with its direct conversion to a series of unusual 5-(1-benzotriazolyl)pyrimidines, 4-(1-benzotriazolyl)-pyrazoles, and 4-(1-benzotriazolyl)pyrroles.
