摘要
Hydrothermal reaction of zinc nitrate, 4-(4-carboxyphenoxy)phthalate acid (H(3)cpop), and different N-donor coligands has afforded six novel supramolecular compounds, in which the nature of the neutral coligands plays a crucial structure-directing role. [Zn(Hcpop)(H2O)(3)](n) (1) and [Zn(Hcpop)(phen)(H2O)](n) (2, phen = 1,10-phenanthroline) form three-dimensional (3D) supramolecular frameworks linked by H-bonds and pi-pi interactions based on discrete molecules. Similarly, [Zn-2(Hcpop)(2)(4,4'-bpy)(3)(H2O)(2)](n)center dot 4nH(2)O (3) possesses a 3D supramolecular structure, aggregated by interesting one-dimensional (1D) armed-polyrotaxane chains. [Zn-6(cpop)(4)(4,4'-bpy)(2)(H2O)(2)](n) (4, 4,4'-bpy = 4,4'-bipyridine) exhibits a complicated 3D framework, which can be rationalized as a (3,6,6)-connected trinodal net with a unique (4.6(2))(2)(4(2).6(9).8(3).10)(4(4).6(8).8(3)) topology. [Zn-3(cpop)(2)(bpdb)(H2O)(2)] (5, bpdb = 1,4-bis(4-pyridyl)-2,3-diaza-1,3-butadiene) is a 3D structure containing two-dimensional (2D) metal carboxylate layers motifs, which are further pillared by cpop(3-) and bpdb ligands to complete the structure. [Zn-6(cpop)(4)(azpy)(2)(H2O)(4)](n) (6, azpy = 4,4'-azopyridine) manifests a unique quadruple layer structure constructed from two types of bilayered architectures linked by Zn2+ ions and bridging azpy ligands. Meanwhile, solid-state properties such as thermal stability and the photoluminescence properties at room temperature for these complexes have also been systematically investigated.
