The present invention relates to a thermal-crosslinkable hole-transferring polymer and a polymer organic electronic device using the same. To obtain a highly efficient and long-lived polymer organic electronic device for a solution process, the present invention provides a thermal-crosslinkable polymer material which can be formed in a multilayer structure. In particular, a triphenylamine (TPA) group and a carbazole group which have excellent hole-transferring characteristics are induced in order to increase hole movement, and a vinyl group is induced in order to apply crosslinking characteristics. The thermal-crosslinkable hole-transferring polymer of the present invention is induced between a hole feeding layer and a light-emitting layer so as to serve as an interface layer for improving the efficiency of the device by adjusting the hole and the flow of electrons. It has been confirmed that a polymer organic light-emitting device having the interface layer has remarkably improved light-emitting efficiency and an extended lifespan. |
