Exploring the hidden potential of a methoxy substituted HBT derivative as an efficient example of coupling of AIE and ESIPT process and as an energy harvesting platform

Abstract

A methoxy substituted HBT derivative, namely 2-(benzo[d]thiazol-2-yl)-6-methoxyphenol (TMP) was synthesized and characterized. Detailed photophysical investigation of TMP furnished the coupling of excited state intramolecular proton transfer (ESIPT) as well as aggregation induced emission (AIE). The crystal structure analysis along with theoretical calculations on TMP showed equal preference of the proton to form hydrogen bonds with methoxy oxygen and benzothiazole N atom which is responsible for the observed AIE. TMP could be used as an efficient energy harvesting platform with Rhodamine-B dye in aqueous solution, owing to FÖrster Resonance Energy Transfer (FRET) between the two. Finally, TMP can serve as an efficient probe for selective detection of Sulfide in pure aqueous solution as well as in solid state.
