Abstract
A new d m -based metal organic framework (MOF)1Zn(L)(0.5)(bpz)center dot 2H(2)O](n) (1) and another d(9)-based MOF [Cu-4(L)(2)(2,2'-bipy)(4)center dot 5H(2)O](n) (5,5'-(1,4-phenylenebis(methyleneoxy))diisophthalic acid (H4L) 3,3',5,5'-tetramethy1-4,4'-bipyrazole (bpz), 2,2'-bipyridine (2,2'-bipy)) were synthesized under solvothermal conditions and characterized. The single-crystal X-ray analyses showed that the CP 1 had an uncommon 2D network comprising two-fold interpenetrating unit. In contrast, 2 possess binodal (4,4)-connected topology having point symbol (4(2).6(4))(4)(6(4).8(2)). The photocatalytic properties for both frameworks showed that they can photodegrade methyl violet (MV) in UV light. The investigations indicated that both CPs possess good stability and displayed good efficiency as photocatalyst to degrade organic dye under UV light irradiation. The plausible mechanistic pathway through which these MOFs displayed photocatalysis have been suggested through band gap calculations.
