a ESR spectra of solid DBTB-DETH-COF before irradiation and after irradiation. b ESR of DBTB-DETH-COF in the presence of TEMP. c ESR of DBTB-DETH-COF in water with the presence of DMPO. d ESR of DBTB-DETH-COF in methanol with the presence of DMPO. (the black line represents the DBTB-DETH-COF in the dark. The orange line represents that the DBTB-DETH- COF remains yellow after being illuminated for 1 min. The olive line represents the sample displays olive color illuminated for 5 min).
