Square grids pillared with anionic linkers are highly amenable to crystal engineering strategies and offer families of 'platforms' for systematic investigation of gas sorption. Such frameworks, which typically exhibit pcu topology, can offer exquisite control over pore size and functionality. We have developed this platform in such a manner that we have observed highly selective carbon capture in narrow pore pillared grids based upon saturated metal centers (SMCs). Structural and physical properties will be presented.
