a PL spectra and b energy levels of t-COF, b-COF, and a-COF. c ECL curves of three COFs modified GCEs in 0.10 M PBS (pH = 6.8) containing 20 mM TPrA (photomultiplier tube voltage = 700 V). Scan rate: 0.10 V s−1. Inset: Magnified ECL curves of b-COF and a-COF. HOS and LUS of d t-COF, e b-COF, and f a-COF in top view. Isosurface is set to be 0.001 e bohr−3.
