title: pKa Modulation in rhodamine based probes for colorimetric detection of picric acid.
abstract: Tuning the pKa in acid sensitive rhodamine spirolactam derivatives as a function of the solvent medium resulted in the selective detection of picric acid from its lower nitro phenolic analogues and a few other carboxylic acids.
