N2 - An electrochemical quercetin (Q.R.) sensor based on carbon nitride (CN) copolymerized with 2,6-diaminoantandantquinone (DAQ) was assembled. The product has a humongous texture and excellent processability. The as-synthesized samples with uniform surface distribution were characterized by UV-Vis-spectroscopy, PL, XPS NMR, EPR, XRD, FT-IR, BET, and SEM. Furthermore, samples were electrochemically pickled in 0.1 MPBS solution via cyclic voltammetry (CV) for Q.R. electrochemical response, interference research, electrochemical active surface determination, stability, photocurrent and EIS. It was found that current response surges in a linear way with increasing Q.R. concentration from 0.015 µM to 260 µM with less than 2 s of response time and a recognition limit of 0.0025 µM. To assess this sample's feasibility to be used as a sensor, Q.R. content was determined in different real samples comprising green drink, fresh apple, lamella, and reasonable results were achieved. The current study proposed a new approach for identifying Q.R. as well as a novel breed of electrochemical detecting material.
