Abstract

A water-soluble substituted thiourea amphiphile detects mercury with a Turn-On emission signal. Desulfurization-directed mercury sensing in water has been resolved with spectral studies. The amphiphilic thiourea shows appreciable selectivity and sensitivity among other cations and heavy metals, contrary to its control compound in aqueous media. The asymmetric tripodal can self-assemble into ribbon-like morphology in aqueous media, which has been outlined by microscopic analysis. The analytical utility of the tripodal has been probed through real water samples and soil testing. Moreover, the Hg-ensemble selectively recognizes H2S viz; sulphide ion in water and rendering a substantially low detection limit of 0.5 ppm. Realistically, paper strips are set for the fluorimetric visualization of both the analytes.
