摘要

Pure organic luminogens with room temperature phosphorescence (RTP) have drawn much attention due to their fundamental importance and promising applications in optoelectronic devices,bioimaging,sensing,etc.Fluorescence-phosphorescence dual emission at room temperature,however,is rarely observed in pure organic materials.Herein,we reported a metal-and heavy-atom free pure organic luminogen with tert-butyl groups,DtBuCZBP,which is ready to form organogels in dimethylsulfoxide (DMSO).It emits prompt and delayed fluorescence,as well as RTP,namely dual emission in as-prepared solid,gels and polymeric films.To the best of our knowledge,it is the first example of metal-and heavy-atom free pure organic gelator with RTP emission.Such unique RTP and moreover dual emission properties in different states make DtBuCZBP a potential material for diverse applications.
