“…Electron-withdrawing substituents such as fluorine in 1,3- β -diketone pyrazolone improve the electronic properties of the ligand [ 24 ]. As supported by Ghoneim et al [ 25 ], the enol from the OH of the acyl pyrazolones is mildly acidic, making it appropriate for electrochemical sensing applications and has practical importance in polarographic detection of trace metals [ 26 , 27 ]. Recently, no endeavours have been made to develop the HPMpFP for the improvement of the electrochemical glucose sensor.…”

In this work, a novel electrochemical sensor was developed by electron-withdrawing substituent modification of 1-phenyl-3-methyl-4-(4-fluorobenzoyl)-5-pyrazolone on a graphene-modified glassy carbon electrode (HPMpFP-graphene/GCE) for glucose detection. The results of characterizations using a scanning electron microscope, Fourier transform infrared spectroscopy, Raman spectroscopy, and nuclear magnetic resonance spectroscopy showed the successful fabrication of HPMpFP-graphene nanocomposite, which served as an electroactive probe for glucose detection. The electron transfer ability of HPMpFBP-graphene/GCE has been successfully revealed using cyclic voltammetry and electrochemical impedance spectroscopy results. The good electrochemical performance was shown by well-defined peak currents of square wave voltammetry under various parameters, including pH, HPMpFP and graphene composition, and scan rate effect. A high electrochemically evaluated surface area using chronoamperometry suggested that the present glucose detection response was intensified. The chronoamperometry results at a work potential of 0.4 V presented a wide linear range of 1 × 103–90 µM and 88–1 µM with 0.74 µM (S/N = 3) as the detection limit. An acceptable recovery has been revealed in the real sample analysis. The electrochemical sensing behaviour of the composite indicates that it may be a promising candidate for a glucose sensor and it significantly extends the range of applications in the electrochemical field.

Triazine‐based molecules have emerged as promising candidates for developing selective and sensitive chemosensors for metal ion detection. Their structural tunability facilitates the introduction of a variety of functional groups, improving their binding affinity and specificity toward a variety of metal ions. This review highlights various sensing mechanisms, including colorimetric and fluorometric methods, and provides insights into the performance of these sensors in terms of sensitivity, selectivity, and detection limits. The synthetic routes for synthesizing the chemosensors are mentioned in detail. Given their reliability and flexibility, triazine‐based sensors are poised to make significant contributions in the field of both sensor and analytical chemistry.
