New conjugated carbazole derivatives: synthesis and photophysical properties catalysed by Pd–Cu@rGO

Abstract

Different wt% of Pd@rGO, Pd–Cu@rGO and Pd–Ni@rGO catalysts were prepared from a one-pot wet chemical method for the synthesis of various conjugated carbazole derivatives via Suzuki–Miyaura cross-coupling reaction and their photophysical properties were screened.
