From: Photo-tailored heterocrystalline covalent organic framework membranes for organics separation
Preparation of heterocrystalline COM by subsequent dark reaction and photo reaction using interfacial polymerization, where the top light-blue layer is the aqueous phase and the bottom navy-blue layer is the organic phase. 1,3,5-triformylphloroglucinol (Tp) and 2,2′-bipyridine-5,5′-diamine (Bpy) are used as aldehyde monomer and amino monomer, respectively, to prepare Schiff-base Tp-Bpy COM. The inset digital photograph is the photo-tailored heterocrystalline COM deposited on non-woven fabrics with the size of ~15 cm × 8 cm (Supplementary Fig. 1).
