| Abstract: | 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. |
