Abstract

In this paper, a novel white-light luminescent material derived from bis(8-hydroxyquinolinato)zinc(II), Zn(2DCDC-HCz-Q)2, was designed and synthesized, which is comprised of bis(8-hydroxyquinolinato)zinc (ZnQ2), 3-(dicyanomethylene)-5,5-dimethyl-cyclohexene (DCDC) and carbazole (Cz) groups serving as yellowish-green-, blue- and red-light emitting units, respectively. The luminescence properties of Zn(2DCDC-HCz-Q)2 were characterized and discussed. Zn(2DCDC-HCz-Q)2 showed remarkable white-light fluorescence, exhibiting CIE coordinates of around (0.32, 0.39) and coloration index of 77.7 %. During the emission process, ZnQ2 unit emits yellowish-green light by induction of the Cz group through Förster energy transfer, and red-light emission is realized by charge transfer from Cz ring to DCDC unit. Hence, Zn(2DCDC-HCz-Q)2 shows a great potential to be used in the fabrication of white-light organic light-emitting device.
