Descrição

A new series of thermally stable benzimidazole-based nonlinear optical (NLO) chromophores 4-5 has been developed. These chromophores possess a thienylpyrrolyl pi-conjugated system attached to functionalized benzimidazole heterocycles. This feature leads to robust chromophores with excellent solvatochromic properties, high thermal stabilities and good molecular optical nonlinearities.
