The exact hosts for F‐P hybrid WOLEDs have been first demonstrated following a new design strategy for blue fluorophors with small singlet‐triplet splitting. Two novel compounds DPMC and DAPSF exhibit efficient blue fluorescence, high triplet energies and good conductivities. These merits allow us to use new simplified device designs to achieve high efficiency, slow efficiency roll‐off and stable emission
F-P混合WOLED的确切宿主首先遵循具有小单峰-三重态分裂的蓝色荧光团的新设计策略进行了演示。两种新型化合物DPMC和DAPSF表现出有效的蓝色荧光,高三线态能量和良好的电导率。这些优点使我们能够使用新的简化设备设计来实现高效率,慢速滚降和稳定的发射颜色。
