Abstract
- Two highly stable metal–organic frameworks (MOFs) assembled by a flexible 1,4-bis(2-methylimidazol-1-yl)butane (bib), and two different aromatic carboxylate coligands, namely, [Zn(BDC–OH<subscript>2</subscript>)(bib)] (1) and [Cd<subscript>3</subscript>(BTC)<subscript>2</subscript>(bib)(DMF)<subscript>3</subscript>] (2) (H<subscript>2</subscript>BDC–OH<subscript>2</subscript> = 2,5-dihydroxyterephthalic acid, H<subscript>3</subscript>BTC = 1,3,5-benzenetribenzoic acid), were designed and synthesized. 1 showed a 4-fold interpenetration of 4-connected dia-type topological net. In 2, the 3D topological structure can be viewed as a (3,4,5)-connected network, and its Schläli point is {4·6<superscript>2</superscript>}<subscript>2</subscript> {4<superscript>2</superscript>·6·8<superscript>3</superscript>} {4<superscript>6</superscript>·8<superscript>9</superscript>}. Different auxiliary carboxylate ligands were examined with respect to the building of various structures. 1 and 2 have outstanding photocatalytic behaviors for the disintegration of methyl violet (MV) under UV irradiation.
