Identifying Solid Luminogens through Gold‐Catalysed Intramolecular Hydroarylation of Alkynes

Abstract

The identification of a new class of luminogens based on pyrrolo‐quinoxaline embedded coumarin (PQC) structures is reported. The reaction relies on the gold‐catalyzed hydroarylation reaction of appropriately substituted aryl alkynoates that produces molecules that exhibit solvatochromism and aggregation‐induced emission enhancement (AIEE) phenomena. The application of PQCs for live cell imaging has also been demonstrated.
