New class of imidazoles incorporated with thiophenevinyl conjugation pathway for robust nonlinear optical chromophores
摘要:
A new series of thermally stable heterocyclic imidazole-based nonlinear optical chromophores has been developed. These chromophores possess a thiophene based stilbene conjugation pathway with a nitro acceptor group attached to the phenyl end. This feature leads to robust chromophores with high thermal stability and enhanced molecular nonlinearity. (C) 2001 Elsevier Science Ltd. All rights reserved.
