Abstract

A highly selective thiourea-naphthol based fluorescent chemosensor SC ((E)-2-((8-hydroxy-2,3,6,7-tetrahydro-1H,5H-pyrido[3,2,1-ij] quinolin-9-yl) methylene)-N-(naphthalen-1-yl) hydrazine-1-carbothioamide) for sensing In³⁺ was developed. Sensor SC could detect In³⁺ by a fluorescent turn-on method in aqueous solution. The detection limit of SC for In³⁺ is calculated to be 9.62 μM. In addition, sensor SC successfully functioned as a visible fluorescent test kit for detecting In³⁺, and quantification of In³⁺ was also successful in real water samples with satisfactory recovery. Sensing mechanism of SC towards In³⁺ was identified by fluorescent and UV–vis titrations, FT-IR, NMR titration, ESI-MS and theoretical calculations.
