CHARGE TRANSPORTING MATERIAL FOR USE OF ORGANIC ELECTROLUMINESCENCE ELEMENT CONTAINING CARBAZOLYL GROUP AND ITS USE

摘要

PROBLEM TO BE SOLVED: To provide a charge transporting material for use in an organic EL element whose molecules are hardly crystallized even with high Tg and which has excellent characteristics such as low voltage drive and a long service life when used as a material for the organic EL element. SOLUTION: The charge transporting material for use in an organic electroluminescence element has a carbazolyl group expressed by a general formula [1], where X refers to a linking group having a fluorene group.
