Abstract

Herein, we report a highly fluorescent material 3,4-bis(4'-(9H-carbazol-9-yl)-1,1'-biphenyl]-4-yl)-1-hexyl-1H-pyrrole -2,5-dione (Cbz-MI) based on donor-pi-acceptor-pi-donor (D-pi-A-pi-D) backbone. We explored maleimide as an acceptor, phenyl as pi-conjugated spacer and carbazole as donor. Photophysical properties revealed high photoluminescence quantum yield of 0.84 and 0.72 in solution and doped matrix, respectively. An encouraging external quantum efficiency of 2.5% with emission peak at 550 nm is achieved utilizing Cbz-MI as emitting layer in doped electroluminescent device structure: (C) 2016 Elsevier B.V.
