New substituted 1,2,3-triazoles for ratiometric recognition to Fe3+ ions.
Two novel click derived sensory systems for different derivatives connected via a triazole linkage have been developed as a component of a chemosensor with sensitive towards Fe3+ ions. The 1-octyl-4-carboxyl-1,2,3-triazole (TR1) system demonstrated sensitivity to calcium ion. The 1,3-bis(4-hydroxycarbamoyl-1,2,3-triazol-1-yl)xylylene (TR2) system was shown to possess a preferential detection capability as a colorimetric probe for Fe3+ ions by exhibiting an obvious pH-dependent color change from colorless to pink. Complexation of the ligands with Fe3+ ions was studied. The 1:1 stoichiometry and bonding sites of TR1-Fe3+, and TR2-Fe3+ complexes were elucidated by analyzing the Job plot. The association constants of 5.35 × 105 M1 for TR1- Fe3+ and 3.58 × 104 M1 for TR2-Fe3+ and detection limits 1.68 × 10-8 and 2.52 × 10-7 were determined from standard deviation and linear fittings.
