TRIAZOLE DERIVATIVE AND ORGANIC ELECTROLUMINESCENT ELEMENT PRODUCED THEREFROM

摘要

A triazole derivative represented by general formula (1); and an organic electroluminescent element having a layer containing a triazole derivative represented by general formula (1) or (2). The derivative is excellent in electron transport efficiency, hole blocking and heat resistance, and the element is excellent in luminescence efficiency, luminance and stability. In said formulae (1) and (2) the symbols are each as defined in the specification.
