Abstract

The bright white lights: A series of highly robust platinum(II) complexes supported by tetradentate O N C N ligands with high emission quantum yields (0.72-0.93) and high T(d) (>400 °C) have been synthesized. Among the complexes, that shown in the figure has strong excimer emission attributed to the monomer triplet excited state with a localized structure. The application of this low band-gap material on single-dopant organic or polymer white-light-emitting diodes (WOLED) is highlighted.

摘要

明亮的白色灯光

一系列高度坚固的铂 (II) 配合物，由四齿 ONCN 配体支持，具有高发射量子产率（0.72-0.93）和高 T(d)（>400°C）。在这些配合物中，如图所示的配合物具有归因于单体三重态激发态的强激基复合物发射，其具有局域结构。这种低带隙材料在单掺杂有机或聚合物白光发光二极管（WOLED）中的应用被强调。
