BENZODITHIOPHENE DERIVATIVE AND ORGANIC ELECTROLUMINESCENT ELEMENT PRODUCED BY USING THE BENZODITHIOPHENE DERIVATIVE AS LUMINESCENT LAYER

摘要

PROBLEM TO BE SOLVED: To provide a benzodithiophene derivative having excellent luminescent efficiency and stability in the case of using as a luminescent layer of an organic EL element, and easily synthesizable to reduce the production cost. SOLUTION: A benzodithiophene derivative expressed by formula (1) (R1 is hydrogen, an alkyl or phenyl) is synthesized and used as a luminescent layer. COPYRIGHT: (C)2007,JPO&INPIT
