Fig. 3

a UV-vis DRS spectra and (b) schematic band alignments of CN-COFs. c ECL curves of CN-COFs modified GCEs in 0.10 M PBS (pH = 7.4) containing 20 mM K2S2O8 (PMT = 400 V). Scan rate: 0.10 V s−1. Inset: Magnified ECL curves of three COFs. HOMO-1, HOMO, LUMO, and LUMO + 1 of (d) CN-COF-1, e CN-COF-2, and f CN-COF-3. Blue and Red dotted boxes represent the HOMO and LUMO distribution, respectively.
