Title: HOLE-ONLY SEMICONDUCTOR DIODE DEVICE BASED ON ASYMMETRIC ORGANIC HOLE TRANSPORT MATERIAL
Abstract:
Provided is a hole-only semiconductor diode device based on an asymmetric organic hole transport material, comprising an anode (20), a cathode (60), and an organic layer. The organic layer is one or more of an electron blocking layer (50), a hole transport layer (40), and a hole injection layer (30). The organic layer has a compound of formula (I), wherein R1 and R2 are each independently selected from hydrogen, an alkyl having 1 to 8 carbon atoms, an alkylene having 2 to 8 carbon atoms, an alkynyl having 2 to 8 carbon atoms, or an aryl having 5 to 20 carbon atoms. The compound has a high glass transition temperature and a high thermal stability, and a hole-only semiconductor diode device prepared therefrom has good and stable performance and a long device lifetime.
