Development of novel strategies for achieving amorphous ultralong organic phosphorescence (UOP) at room temperature is highly desired. Herein, a simple approach is reported by coassembling small organic molecules with polyvinyl alcohol (PVA) to afford amorphous UOP. These small organic molecules with planar conformation present quenched triplet state emission in an excessive stacking solid state....
In article number 1807243, Yanli Zhao and co‐workers develop a strategy to confine planar small organic molecules using polyvinyl alcohol (PVA), where the molecular rotation and vibration of these molecules are restricted in the coassembly, achieving ultralong room temperature phosphorescence. Thus, coassembling multicomponent luminescence dyes with PVA leads to multicolor and flexible luminescence...
