Crystal structure and fluorescence of 1-[8-phenyl-9-(phenylethynyl)-4H-benzo[def]carbazol-4-yl]ethan-1-one

Abstract

The crystal of the title compound, C60H38N2O2, which crystallizes in the monoclinic space group P21/n, was obtained by thermal evaporation of a 1:1 dichloromethane and hexanes solution of the pure compound. The crystal structure is stabilized by π–π interactions between benzo[def]carbazole moieties and carbonyl–carbonyl interactions between the two acetyl groups.
