A series of functionalized imidazophenthridine analogue-based blue phosphorescent emitters have been designed, where bulky substituents (e.g., tetrabutyl, phenyl, mesityl, triisopropylbenzene, etc.) are introduced on an imidazophenthridine fragment of the emitters. Bulky substituents may suppress potential excimer formation, as well as improve the solubility of the complexes. This class of emitters may be utilized in luminescent labels, emitters for organic light emitting devices, and lighting applications.
已设计了一系列基于官能化咪唑芘啉类蓝色磷光发射体,其中在发射体的咪唑芘啉片段上引入了大体积取代基(例如四丁基、苯基、二甲苯基、三异丙基苯等)。大体积取代基可以抑制潜在的激聚体形成,并改善配合物的溶解性。这类发射体可以用于发光标签、有机发光器件的发射体以及照明应用中。
