摘要： An organic light-emitting device comprises an anode; a hole injection layer in contact with the anode; a light-emitting layer over the hole injection layer; and a cathode over the light-emitting layer, wherein the hole injection layer comprises an organic semiconductor material doped with a partially fluorinated fullerene such as C60. The dopant is present in the range of about 0.1-20 wt %, optionally 0.1-5 wt %. The organic semiconductor is preferably a polymer comprising repeat units of formula (I): wherein Ar1 and Ar2 in each occurrence are independently selected from optionally substituted aryl or heteroaryl groups; n is greater than or equal to 1, preferably 1 or 2; R is H or a substituent; any of Ar1, Ar2 and R may be linked by a direct bond or linking group; and x and y are each independently 1, 2 or 3.
