Functionalized Schiff-base containing phenothiazine and cholic acid as a paper-based fluorescence turn-off sensor for Sn(ii) ion detection and its application

Abstract

The development of the cholyl hydrazide Schiff base of phenothiazine as a paper-based sensor for the detection of Sn(ii) ions with chelation-enhanced fluorescence quenching sensing mechanism and its possible integration into a logic gate system.
