Scheme 1. Schematic diagram of dual-pore 2D COFs with dual linkages constructed by a “three-in-one” strategy. COFs: Covalent organic frameworks; ADTB: (4-amino-4"-(2,2-dioxan-1,3-dioxan-5-yl)-[1,1':3',1"-terphenyl]-5'-yl) boronic acid; ADPB: (4'-amino-5'-(4-(2,2-dioxan-1,3-dioxan-5-yl)phenyl)-[1,1':3',1'-teroxan]-5-yl) boronic acid.
