BITHIOPHENE DERIVATIVE FOR GREEN ORGANIC LIGHT-EMITTING DIODE DOPANT AND METHOD FOR PREPARING THE SAME

摘要

A bithiophene derivative for green organic light-emitting diode dopant and method for preparing the same are provided to have an excellent thermal stability, color purity, and light efficiency and to have superior photophysical characteristics as a dopant in an organic light-emitting diode. The bithiophene derivative of the present invention comprises a bithiophene with an end cap of 2,2-diphenylvinyl connected with an arylamine residue of 9-phenylcarbazole, triphenylamine, or N,N′-di-(p-tolyl) benzeneamine.
