Abstract

An integrated selective probe CNS (E)-2-(((9-octyl-9H-carbazol-3-yl)imino)methyl)naphthalen-1-yl-2,4-dinitrobenzenesulfonate) possessing active sulfonate ester moiety was successfully designed. The probe CNS owns a greater potent over H₂S analyte even in the presence of other competing analytes with its excellent spectral performances like excellent absorbance and emission properties. In addition, the probe CNS detects and quantifies H₂S analyte up to the concentration of 7.40 × 10⁻¹⁰ M and 2.4 × 10⁻⁹ M with the response time of 60 s (1 min) based on active ESIPT process. Moreover, the probe CNS was utilized towards the environmental and biological monitoring of H₂S.
