Triazole-based novel bis Schiff base colorimetric and fluorescent turn-on dual chemosensor for Cu²⁺ and Pb²⁺: application to living cell imaging and molecular logic gates.

ABSTRACT: A triazole-based novel bis Schiff base colorimetric and fluorescent chemosensor (L) has been designed, synthesized and characterized by elemental analysis, ¹H-NMR, ESI-MS, FTIR spectra and DFT studies. The receptor L showed selective and sensitive colorimetric sensing ability for Cu²⁺ and Pb²⁺ ions by changing color from colorless to yellow and light yellow respectively in CH₃OH-tris-buffer (1 : 1, v/v). However, it displayed strong fluorescence enhancement upon the addition of both Cu²⁺ and Pb²⁺ ions, attributed to the blocking of PET. The fluorometric detection limits for Cu²⁺ and Pb²⁺ were found to be 12 × 10^-7 M and 9 × 10^-7 M and the colorimetric detection limits were 3.7 × 10
