NOVEL BIS(CARBAZOLYLPHENYL) DERIVATIVE, HOST MATERIAL, AND ORGANIC ELECTROLUMINESCENT ELEMENT EACH EMPLOYING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a novel bis(carbazolylphenyl) derivative that enables driving of an element at a low voltage and is required in providing a highly efficient element, a host material employing the same, and an organic electroluminescent element employing the same. SOLUTION: The bis(carbazolylphenyl) derivative is represented by formula (1). The host material and the organic electroluminescent element each employ the novel derivative.
