  摘要：

  Three new 2D zinc-organic frameworks, [Zn-3(L1)(3)(DMF)(2)](n) (1), [Zn(L2)(BPP)](n) (2) and [Zn-2(L3)(2)(BPP)](n)center dot nDMF (3), (L1 = 2,5-dimethylterephthalate, L2 = 2-aminoterephthalate, L3 = terephthalate, BPP = 1,3-bis(4-pyridyl)propane, DMF = N,N-dimethylformamide), have been prepared and characterized. Complex 1 consists of trinuclear zinc clusters connected to six L1 ligands, in which the trinuclear clusters act as pseudo-planar hexagonal nodes to give a 2D network. In complex 2, two 4(4)-sql nets interlock in parallel and give rise to a polycatenated layer (2D -> 2D). Complex 3 features a 2D (4,4) net when the dinuclear [Zn-2(COO)(2)N2O2] unit is regarded as a quadruply-connected node. These results indicate that the steric effect of 1,4-benzenedicarboxylates substituents has an important effect on the structural topologies of such Zn(II) complexes. All of 1-3 emit the intense indigotin photoluminescence at room temperature, with lifetimes of 28.04, 3.08 and 2.43 ns, respectively. The moisture-stability analyses of 1-3 have also been investigated. (C) 2012 Elsevier B.V. All rights reserved.
