摘要：

Thermal stability of the electroluminescent (EL) devices using various hole-transporting materials based on triphenylamine, and a typical emitting material, tris(8-quinolinolato) aluminum has been systematically studied. The thermal stability of the EL devices is clearly seen to depend on the glass transition temperature (T-g) Of the hole-transporting material. The highest thermal stability up to 155 degrees C is obtained in the device using the pentamer of triphenylamine. It has been found that the linear linkage of triphenylamine is useful to attain high T-g rather than the branch linkage. (C) 1997 American Institute of Physics.
