摘要: 以4,4′-联苯-双膦酸单酯(H2BPDP)为有机膦酸配体,通过引入第二有机配体2,2′-联咪唑(H2biim),在水热条件下成功合成了一种新型金属膦酸镉配位聚合物[Cd(BPDP)-(H2biim)2]。[Cd(BPDP)(H2biim)2]为二维超分子层状结构,CPO3四面体与CdO2N4多面体共角相连构成一维Z字形链状结构,相邻的链通过π-π堆积作用形成二维超分子层状结构。同时对[Cd(BPDP)(H2biim)2]的荧光性能进行了研究。

Abstract: In this paper, by employing 4,4′-biphenyldiphosphonate (H2BPDP) as the phosphonate ligand and H2biim as the second metal linker, we have successfully obtained a novel cadmium(Ⅱ) phosphonate with 2D supramolecular structure under hydrothermal condition, namely, [Cd(BPDP)(H2biim)2]. {CPO3} and {CdO2N4} polyhedra are interconnected by phosphonate ligands to form a 1D Z-type chain via corner-sharing. Neighboring chains are linked into a 2D supramolecular layer through π-π stacking interactions. The luminescent property of [Cd(BPDP)(H2biim)2] has been studied.

Key words: metal phosphonate; crystal structure; luminescent property
