【摘要】 配位聚合物由于其结构的多样性及潜在的应用前景近年来受到广泛的关注。我们采用水热法,以手性的氨基酸衍生物(+)-N-对甲苯磺酰-L-谷氨酸(H2tsgluO)为配体,以柔性的联吡啶类配体1,2-联(4-吡啶基)乙烷(bpe)为辅助配体合成了两种锌(Ⅱ)、镉(Ⅱ)的配合物{Zn(tsgluO)(bpe)}n(1)、{[Cd(tsgluO)(bpe)1.5]·H2O}n(2)。配合物1和2都属于单斜晶系,非手性P21/c空间群,具有二维层状结构(如图1所示)。在配合物1中层与层之间进一步通过氢键连接成三维超分子结构。此外,对这两种配合物的荧光性质进行了研究,发现它们都具有潜在的荧光应用价值。
【Abstract】 Coordination polymers recently have received extensive attension due to their remarkable structures and potential applications.Two novel metal-organic frameworks {Zn(tsgluO)(bpe)}n(1)、{[Cd(tsgluO)(bpe)1.5]H2O}n(2) have been hydrothermally synthesized through the reaction of the chiral amino acid derivative(+)-N-Tosyl-L-glutamic acid(H2tsgluO) with divalent zinc and cadmium salts in the presence of flexible dipyridyl-containing ligands(bpe=1,2-bis(4-pyridyl)methane).Compound 1 and 2 both crystallize in the achiral space group P21/c and present two-dimentional(2D) network structure.Compound 1 are further connected by hydrogen bonds interactions to form three-dimentional (3D) supramolecular architecture.Fluorescence properties of the two compounds indicate that they are potential fluorescent materials.
