摘要： An organic electroluminescence device which includes an anode, a cathode, a hole transport layer, an electron transport layer, and at least one organic luminescent medium doped with a pyrazolo[3,4b]quinoxaline derivative is disclosed. The present device provides improved efficiency, and the emission band associated therewith is surprisingly narrow. The improved green emitting organic electroluminescence device exhibits high color purity.

摘要： Organic electroluminescence devices are described, each of which comprises an anode, a cathode, a luminescent layer, at least one hole-transporting layer disposed between the anode and the luminescent layer, at least one electron-transporting layer disposed between the cathode and the luminescent layer, and a substrate present on either the anode or cathode. The luminescent layer in the devices uses as red-emitting materials, salicylaldiminato Schiff bases or their metal complexes based on diaminomaleonitrile and salicylaldehyde derivatives. These organic electroluminescence devices exhibit excellent color chromaticity co-ordinates and good efficiency.
