Structural characterization and surface properties of MF-1 series. a Powder XRD patterns of COF-1 (black), MF-1a (red), MF-1c (green), MF-1d (blue), and MF-1-e (purple). b FT-IR spectra of COF-1 and MF-1a, c-e. The peaks highlighted in cyan are characteristic vibrations from these functional groups. c Water contact angles (CA) of water droplet on the pressed pellet of COF-1 and MF-1a-e. MF-1b′ is the NaHCO3-treated MF-1b that undergoes partial ester hydrolysis
