NOVEL HETEROCYCLE-CONTAINING HYDROXYPHENYL METAL DERIVATIVE, AND ELECTRON INJECTING MATERIAL, ELECTRON TRANSPORTING MATERIAL, AND ORGANIC ELECTROLUMINESCENCE ELEMENT USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a novel heterocycle-containing hydroxyphenyl metal derivative which enables low voltage driving of a device and is necessary for providing a highly efficient device, and an electron injecting material, electron transporting material and an organic electroluminescence element that use the heterocycle-containing hydroxyphenyl metal derivative.

SOLUTION: There is provided a heterocyclic metal (M) derivative expressed by formula (1). In the formula, A represents a pyridyl group of formula (A); and R1to R4each represent hydrogen, alkyl or the like.
