Recently, organic long persistent luminescence (OLPL) has attracted widespread attention as a new luminescence pathway initiated by the exciplex. However, the low quantum yield, few alternative molecules and high fabrication cost seriously slow down the development of OLPL materials. Herein, a series of simple multi-guest/host OLPL materials with a high quantum yield are reported by doping four phenothiazine derivative guest molecules into 9H-xanthen-9-one host matrices. The F-substituted phenothiazine derivative doping system displays highly efficient emission with 46.3% quantum yield in air. Meanwhile, these OLPL materials provide broad opportunities for further application in the field of heat resistance due to their highly efficient luminescence at high temperatures.

基于主客体掺杂系统的高效有机长持续发光
近年来，有机长持续发光（OLPL）作为一种由激基复合物引发的新型发光途径引起了广泛关注。然而，低量子产率、少数替代分子和高制造成本严重减缓了OLPL材料的发展。在此，通过将四种吩噻嗪衍生物客体分子掺杂到 9 H -xanthen-9-one 主体基质中，报道了一系列具有高量子产率的简单多客体/主体 OLPL 材料。F-取代的吩噻嗪衍生物掺杂体系在空气中显示出高效的发射，量子产率为 46.3%。同时，这些OLPL材料由于其在高温下的高效发光，为进一步在耐热领域的应用提供了广阔的机会。
