中文摘要：

研究了螯合电磷光聚合物PFBtpIrm的光致发光、电化学和电致发光特性,并通过优化器件结构提高聚合物的电致发光性能.发现在聚合物中加入PBD使发光效率降低;而加入PVK空穴传输层后,由于能量有效地转移到电磷光聚合物中,器件性能提高.基于器件ITO/PEDOT/PVK/PFBtpIrm5/Ba/Al,在电流密度为10.0mA/cm2时,最大外量子效率为4.25%,饱和红光的色坐标为（0.69,0.29）.

英文摘要：

Photo luminesence, electrochemical and electroluminescent properties of the chelating electrophosphorescent polymers with red light-emission were investigated in this paper. The device performances of the polymers were improved by optimizing the structure. Mixing PBD in emission layer was found to decrease the luminous efficiency, but the device performances were enhanced by inserting PVK layer because of the energy transfer from PVK to the chelating polymer. The best performance was achieved in device ITO/PEDOT/PVK/ PFBtpIrmS/Ba/Al with the maximal external quantum efficiency of 4.25 at the CIE coordinates of （0.69,0.29）.
