Solvent-induced single-crystal to single-crystal transformation of a 2D coordination network to a 3D metal-organic framework greatly enhances porosity and hydrogen uptake.
Exposure to CH(2)Cl(2) at room temperature induces single-crystal to single-crystal transformation of the 2D coordination network [Zn(2)L(DMF)(4)]·2DMF·4H(2)O to the 3D metal-organic framework [Zn(2)L(H(2)O)(2)]·xsolv via dimerization of the metal-connecting points, leading to significant enhancement in framework stability, porosity, and H(2) uptake capacity.
