摘 要:Supramolecular organic frameworks(SOFs),due to the atomically precise integration of the repeated building units,exhibit intriguing properties and consequently potential applications in chemical and materials science ***,it remains a great challenge to achieve SOFs with ultralong organic phosphorescence(UOP)in a singlecomponent ***,we report metal-free organic compound 9,9′-(6-(2-bromophenethoxy)-1,3,5-triazine-2,4-diyl)bis(9H-carbazole)(DCzPO)with UOP *** to the combination of multiple supramolecular interactions,DCzPO formed a SOF structure with regular hexagonal holes,which shows an ultralong emission lifetime of 398 ms and a phosphorescence efficiency of 3%.So far as we know,among the reported luminescent SOFs,this one is the most highly *** single-component SOF with ultralong phosphorescence will provide a new platform to rationally combine UOP and porous materials.
