NOVEL PHENYL-FLUORENE DERIVATIVES AND ORGANIC ELECTROLUMINESCENT DEVICE COMPRISING THE SAME

摘要

PURPOSE: A phenyl-fluorene derivative is provided to realize excellent hole transport ability, high the luminous efficiency and luminescent brightness, and long lifetime, thereby improving driving voltage, luminous efficiency and lifetime property of an organic electroluminescence device. CONSTITUTION: A phenyl-fluorene derivative has a structure represented by chemical formula 1. In chemical formula 1, R^1 and R^2 are independently hydrogen, C1-30 alkyl or cycloalkyl group containing or not containing at least one hetero atom selected from the group consisting of S, N, O, P and Si, C1-10 alkenyl, aryloxy or arylalkyl- substituted aryl group; an aryl group C1-10 alkenyl, aryloxy or arylalkyl substituted with containing or not containing at least one hetero waters.
