The synthesis of ionic olefin linked threedimensional covalent organic frameworks (3D COFs) is challenging because of the difficulties in forming stable carbon-carbon double bonds. Here, the authors report a general synthesis of an ionic sp2 carbon linked COFs and demonstrate selective capture of ReO4− ions.
