Novel oxacalix[2]arene[2]triazines with thermally activated delayed fluorescence and aggregation-induced emission properties

New kinds of oxacalixarenes based on the triazine moiety have been synthesized, which showed highly twisted conformations and small Δ E ST , as well as temperature-dependent transient PL decay curves, indicating the excellent thermally activated delayed fluorescence properties. Moreover, the oxacali...

Description
Summary:New kinds of oxacalixarenes based on the triazine moiety have been synthesized, which showed highly twisted conformations and small Δ E ST , as well as temperature-dependent transient PL decay curves, indicating the excellent thermally activated delayed fluorescence properties. Moreover, the oxacalixarenes also exhibited apparent aggregation-induced emission properties in THF/H 2 O mixtures. Novel triazine-based oxacalixarenes were designed and synthesized, and they exhibited excellent TADF properties and apparent AIE characteristics in THF/H 2 O mixtures.
