A dinuclear cyclometalated iridium-platinum complexIridium[Ⅲ]bis[(2,4-difluorophenyl)-pyridinato-N,C^2'] [picolinate]-C6-Paltinum[II] [phenylpyridinato-N,C²'] [picolinate](FIrPPyPt) was designed and synthesized. Its structure and properties were characterized by NMR, elemental analyzer, UV absorption spectroscopy and photoluminescence spectroscopy. The results show that the UV absorption of the complex FIrPPyPt is located between 250 and 450 nm, and the fluorescence emission peak is located at 465 and 493 nm. The electroluminescent devices were made from poly(N-vinylcarbazole)(PVK)+2-(biphenyl-4-yl)-5-(4-tert-butylphenyl)-1,3,4-oxadiazole(PBD) doped with 1%~8% mass fraction of FIrPPyPt complexes. The electroluminescence spectra at different voltages show the characteristic peaks of iridium complexes and platinum complexes located at 400, 500 and 530 nm in blue-green emission zones. The dual core complexes are used for single doped organic white light emitting devices with simple fabrication, good color stability and good reproducibility, it provides a good idea for the single doped white light emitting devices.
