DOI: 10.1016/j.chemphys.2019.01.008
Abstract: Abstract The -OH group protected 2-(hydroxyphenyl) benzothiazole (HBT) based ratiometric chemodosimeters have previously been reported to undergo regeneration of excited state intramolecular proton transfer (ESIPT) process upon deprotection. In the current work it is demonstrated… read more here.
