Unveiling Interference-Free Acridine-Calix[4]Arene-Based Fluorescence paper and Electrochemical Sensor for Cyanazine from Agricultural Produces
The construction of fluorescence sensor L1 for cyanazine (CNZ) by using calix[4]arene scaffold allied with 9-Aminoacridine moiety has been reported. The recognized triazine herbicide CNZ decreased the fluorescence intensity of L1 by exhibiting “turn-off” phenomenon having detection limit to be 7.79 μM obtained from emission study. The quenching response of L1: CNZ was observed between the range of 5–105 μM possessing binding constant calculated to be 9.201×106 M−1. The spiking experiment of CNZ into L1 has also been performed to evaluate potency of L1 using vegetables and cereals. Also, a paper-based device has been prepared in order to implement this strategy for on-spot monitoring of CNZ. The L1:CNZ binding has been confirmed by conducting electrochemical studies like cyclic voltammetry, differential pulse voltammetry, 1H NMR, FT-IR, MALDI-TOF, 1H NMR titration, PXRD investigation and computational analysis.
