Their molecular mass was measured by gel permeation chromatograph, chemical structure was characterized by 1H NMR, and the photophysical property, thermal stability and electrochemical property of these polymers were investigated by UV absorption spectra, fluorescence spectra, thermogravimetric analysis and cyclic voltammetry. Using the polymers as emitting layer, the devices were made with a configuration of ITO/PEDOT: PSS (50 nm)/ PFCzIrpiq (45 nm)/LiF(0.5 nm)/Al (150 nm), and their electroluminescent properties were measured. The results show that the molar percentage of (Piq)2Ir(Pic) in these polymers has great influence on light-emitting color of these polymers. When the molar percentage was 1%, the device exhibited blue emission with a CIE coordinate of (0.22, 0.22); when the percentage was increased to 5%, the device emitted saturated red light with a CIE coordinate(0.65, 0.35). Furthermore, with the increasing of molar percentage of (Piq)2Ir(Pic), the current density decreased and the maximum brightness increased gradually. When the molar percentage was 5%, the maximum brightness of 48 cd/m2 was achieved.
