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, PXRD investigation and computational analysis.
