Organic light-emitting device

Disclosed is an organic electroluminescent device. The organic electroluminescent device comprises an anode, a cathode, a first organic layer and a second organic layer, wherein the first organic layer and the second organic layer are arranged between the anode and the cathode; wherein the first organic layer includes a first compound represented by Formula 1, and the second organic layer includes a second compound represented by Formula 2. The first compound can be used as a light-emitting auxiliary material in an organic electroluminescent device, and the second compound can be used as a host material in the organic electroluminescent device. The electroluminescent device can maintain a low voltage or further reduce the voltage, can improve the efficiency of the device, and provides better comprehensive performance of the device. The invention also discloses electronic equipment comprising the organic light-emitting device. 公开了一种有机电致发光器件。所述有机电致发光器件包括：阳极，阴极，以及设置在阳极和阴极之间的第一有机层和第二有机层；其中所述第一有机层包含由式1表示的第一化合物，所述第
