a Steady-state photoluminescence spectra of g-CN-U, g-CN-U/substrate, g-CN-U/base, and g-CN-U/substrate/base in CHCl3 (λexc = 390 nm). b Stern-Volmer analysis of the steady-state emission intensity at 450 nm (λexc = 390 nm) with varied substrate concentration. c CVs obtained in a 0.1 M tetrabutylammonium hexafluorophosphate solution containing 2 mM substrate, 2 mM base, and CN as working electrodes (WE). d Zeta potential of the samples under various pH values.
