Fig. 5: Competitive oxidation ECL mechanism of t-COF.

a ECL and PL spectra of t-COF. Inset: ECL images of t-COF at the applied potential of +1.40 V in 100 mM TPrA solution. b The difference of t-COF charge density between 1st excited state and ground state. Electron density gain and loss are donated as blue and red, respectively. c Relative energy and d density of states of t-COF doped with different electron numbers. e Schematic illustration of ECL I and II generation mechanism via intrareticular charge transfer.
