Abstract

Photolysis of aryl azides offers a versatile approach to achieve more sophisticated functionalization, for instance in the field of chemical biology. In this study, a photoactivatable aryl azide named Pcp-Az is presented that forms three distinct emissive molecules after irradiation. Computational studies unveiled that the photolysis of Pcp-Az in aqueous medium undergoes different reaction channels, leading to the three mentioned distinct products. When the photoreaction is performed using the supramolecular host cucurbit[8]uril(CB8) for Pcp-Az, the reaction is found to be tuned and accelerated. Finally, the potential application of the photoproducts are showcased in bioimaging, and also the time-dependent photoactivating imaging.
