Molecular dimers have been frequently found to play an important role in room temperature phosphorescence (RTP), but its inherent working mechanism has remained unclear. Herein a series of unique characteristics, including singlet excimer emission and thermally activated delayed fluorescence, were successfully integrated into a new RTP luminogen of CS-2COOCH to clearly reveal the excited-state process of RTP and the special role of molecular dimers in persistent RTP emission.
分子二聚体经常被发现会在室温磷光(RTP)中发挥重要作用,但其内在工作机制仍不清楚。在此,一系列独特的特性,包括单线态激基缔合物发射和热激活延迟荧光,被成功整合到一种新型的CS-2COOCH室温磷光发光体中,以清晰地揭示室温磷光的激发态过程以及分子二聚体在持续室温磷光发射中的特殊作用。
