Chemodosimetric action in detection of cysteine and homocysteine (310- and 290-fold) and superoxide inputs (336-fold increase) gives significant fluorescence intensity increases. Detection limits of 2.13 × 10–5 M, 1.37 × 10–5 M, and 2.71 × 10–5 M, respectively, are biorelevant and are consistent with “OR” logic gating, demonstrated in intracellular biothiol detection in neuronal cells by way of novel
