An orange-red organic light-emitting diode containing a heptazine derivative exhibits high performance with a maximum external quantum efficiency of 17.5 ± 1.3% and a peak luminance of 17000 ± 1600 cd m⁻² without any light out-coupling enhancement. The high electroluminescence performance can be ascribed to the presence of an efficient up-conversion channel from the lowest triplet state to the lowest singlet state.
一种含有嗪衍生物的橙红色有机发光二极管在没有任何光取出增强的情况下表现出优异的性能，最大外量子效率为 17.5 ± 1.3%，峰值亮度为 17000 ± 1600 cd/m²。高电致发光性能可归因于从最低三重态到最低单线态的有效上转换通道的存在。
