Novel homoleptic cyclometalated Ir(III) complexes designed for high emission dipole orientation (91%) achieved simultaneous enhancement of external quantum efficiency (26.3%, max. calculated 41%) and lifetime (169 h at 1000 cd m⁻², LT80, CIEy 0.30) in blue phosphorescent organic light emitting diodes (OLEDs), see article number 2001103 by Jong Soo Kim, Daun Jeong and co‐workers. Atomistic modelling of the emitting layer reveals that intermolecular interactions between dopant molecules and host matrix depending on their molecular geometries are substantial ingredients to improve the OLED device performances.

蓝色磷光OLED：通过增强均化环金属化Ir（III）配合物的取向来提高蓝色磷光有机发光二极管的效率和稳定性（先进光学材料22/2020）

设计用于高发射偶极子取向（91％）的新型均化环金属化的Ir（III）络合物同时提高了外部量子效率（26.3％，最大计算值41％）和寿命（在1000 cd m ^-2，LT80，CIEy下为169h） 0.30）在蓝色磷光有机发光二极管（OLED）中，请参见Jong Soo Kim，Daun Jeong及其同事的文章编号2001103。发射层的原子建模显示，掺杂剂分子与基质之间的分子间相互作用（取决于它们的分子几何形状）是改善OLED器件性能的重要成分。
