Abstract
The present invention relates to an organic hole transport material having a compound of the structure shown in formula (I), wherein R1-R2 independently represent hydrogen, C1-C8 substituted or substituted alkyl, C2-C8 substituted or unsubstituted alkenyl, C2-C8 substituted or unsubstituted alkynyl, or C6-C10 substituted or substituted aryl, the substituents being C1-C4 alkyl or halogen. Device experiments show that the organic hole transport material of the present invention has high glass-transition temperature and high thermal stability; a hole-only organic semiconductor diode device and an organic electroluminescent device manufactured by the organic hole transport material have good hole transport performance, high and stable current efficiency, and a long device life.
