Abstract |
A 2-(2’-hydroxyphenyl)-4-pyrenyl-thiazole based probe (Probe 1) was designed and synthesized. Probe 1 showed extensively high fluorescence emission intensity centered at 425 nm in DMSO. And showed excimer emission centered at 495 nm in DMSO-Glycerol system (1:9 v/v). Higher emission intensity at 425 nm in DMSO resulted from effective intra-molecular charge transfer (ICT) coupled energy transfer (ET) from pyrene unit to phenylthiazole unit through the structurally bent rigid conformation. In contrast in DMSO-Glycerol system (1:9 v/v) simultaneous inhibition of ICT-ET occurred from pyrene to phenylthiazole unit with effective stabilization of inter-molecular pyrene units excimer-exciplex complex through the aggregated phenomenon resulted in excimer emission. Further sensing ability of 1 towards anions and its biological applications also demonstrated. |
