Title:
新規含窒素複素環誘導体及びそれを用いた有機エレクトロルミネッセンス素子
Document Type and Number:
Japanese Patent JP4185097
Kind Code:
B2
Abstract:
A novel derivative of heterocyclic compound having nitrogen atom with a structure made by bonding special groups to benzimidazole, a material for an organic electroluminescence (EL) device comprising the derivative of heterocyclic compound having nitrogen atom and an organic electroluminescence device comprising at least one organic compound layer containing a light emitting layer sandwiched between a pair of electrodes, wherein the device contains the derivative of heterocyclic compound having nitrogen atom. An organic EL device achieving elevation of luminance and of efficiency in light emission even under low driving voltage is obtainable by an employment of the derivative of heterocyclic compound having nitrogen atom for at least one layer composing organic compound layers of the EL device.
