Fig. 7

a PXRD pattern of MP-COF-1 synthesized by MIPEC with addition of acetic acid (2.5 mL AcOH, MIPEC), without acetic acid (0.5 mL BMImNTf2 + different water addition, MIPEC; 5 mL water, Non-contact microplasma; No addition, Non-contact microplasma). EPR spectra of the precursor solution (b) with addition of acetic acid (2.5 mL AcOH, MIPEC), (c–d) without acetic acid (0.5 mL ionic liquids + different water addition, MIPEC) before and after treated by MIPEC, DMPO = 100 mM. The EPR signals of DMPO-•OH, DMPO-n-BuO•, DMPO-•CH2CH2OH are marked as yellow circle, red diamond and orange star, respectively. e–f without acetic acid (No addition, Non-contact microplasma; 5 mL water, Non-contact microplasma) before and after treated by Non-contact microplasma. g The proposed formation mechanism of MP-COF-1 with ROS generated by MIPEC.
