Abstract/OtherAbstract:
Co-precipitation of 1,4-bis(2-phenyl-1-propen-1-yl)benzene (1) and 2-(4-(2-(4-(3,6-di-tert-butyl-9H-carbazol-9-yl)phenyl)ethynyl)benzylidene) malononitrile (2) that individually form blue-emitting and orange-emitting nanoparticles, respectively, results in the formation of composite fluorescent organic nanoparticles that emit white light. The two components likely align in the head-to-tail fashion in nanoparticles, creating two parallel and strongly coupled transition dipoles. The emission characteristics of the composite was dependent upon the concentration of 1 and 2, and a pure white-light emission (CIE chromaticity coordinates of 0.34, 0.35) was achieved from the composite that was prepared by employing 12 parts of 1 and 1 part of 2.
