Abstract

A newsworthy class of carboxylate esters based on the (benzo [a] acridin-12-yl) methyl (BAM) chromophore has been shown to perform dual functions as a “pH sensitive fluorescent probe” and a “phototrigger” for acids. The photophysical properties of all the BAM ester conjugates were investigated and found to be highly sensitive to solvent polarity, H-bonding capability and pH of the environment. On irradiation using UV light (≥ 410 nm) ...
