Abstract

A pyrene-mercapto-based fluorescent chemosensor TTP was designed for detecting Ag⁺ with fluorescence variation. The binding mode of TTP to Ag⁺ was determined to be a 2:1 complexation through Job plot and ESI-MS analysis. Detection limit of sensor TTP for Ag⁺ was 76.5 nM. Moreover, sensing process of Ag⁺ with probe TTP was explained by ¹H NMR titration and theoretical calculations.
