摘　　要：以笼型多面体硅氧烷(poss)封端的聚烷基芴PFO-poss和PVK为主体,红光磷光络合物Ir(piq)为客体制作了不同结构的器件,最终在以PFO-poss为主体的双层结构器件当中获得了5.48cd/A的电致发光效率,超过了以PVK为主体的器件效率水平。研究了以PFO-poss为主体的器件中PVK的作用,发现作为空穴传输层的PVK也参与到了能量转移的过程,使得红光的效率大幅度提高。Series of devices have been made based on a poss end capped polyfluorene and poly（N vinylcarazole）（PVK） as the host,a red Ir complex as the guest.An efficiency of 5.48cd/A was achieved,which surpassed that of device based on PVK as the host.The activity of PVK at the device based on PFO-poss as the host was also studied.We found PVK as the hole-transport layer also participate the process of energy exchange,which can raise the efficiency of the device.
