    摘要: The triazole derivatives of this invention are expressed by the general formula (1). The organic electroluminescent device of this invention have a layer containing at least one triazole derivative of the general formulas (1) and (2). Such triazole derivatives are excellent in electron-transport efficiency, hole-blocking properties and heat resistance, and such organic electroluminescent devices are excellent in luminous efficiency, luminance and stability. ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7, R.sup.8, R.sup.9 and R.sup.10 have the same meanings as indicated in the specification.
