摘要：

A novel hole-transporting poly [di(1-naphthyl)-4-tolylamine:DNTA] (PDNTA) has been developed. PDNTA was easily prepared by oxidative coupling polymerization of DNTA using FeCl3 as an oxidant. This polymerization produced regiocontrolled PDNTA with high molecular weights. PDNTA exhibited strong UV-vis absorption bands at 267 and 370 run in chloroform solution. Their photoluminescence spectra showed a maximum peak band around 445-448 nm in the blue region. The organic light-emitting device (OLED) prepared by spin-casting PDNTA solution onto ITO-coated glass substrate in conjunction with Alq and LiF/Al, as an electron-transporting light-emissive layer and a metal cathode, respectively, showed a maximum luminescence of 25 000 cd/m(2) at 12.5 V.
