氢键和π-π诱导的三重穿插的二维Zn(Ⅱ)配位聚合物的晶体结构和荧光性能

摘要

本文以(4-羧基苄基)-4,4’-二羧基二苯胺(H3L)和1,10-菲罗啉(Phen)为配体,溶剂热合成了一个二维锌配位聚合物[Zn(HL)(Phen)]n(1),对其进行了红外、热重、粉末单晶衍射等表征,配合物属于三斜晶系,空间群P21/c.相邻的Zn(Ⅱ)离子通过连接HL2-和Phen形成一维之字形的链,该一维链通过氢键和π-π作用进一步形成三重穿插的二维超分子结构.此外,还研究了配合物的荧光性能.%Solvothermal reaction of 4,4'-[(4-carboxybenzyl)nitrilo]dibenzoate (H3L) with 1,10-phenanthroline (Phen)produced a two dimensional (2D) zinc(Ⅱ) coordination polymer [Zn(HL)(Phen)]n (1).The complex was characterized by elemental analysis,IR spectroscopy,and X-ray single-crystal diffraction.It crystallizes in the monoclinic system,space group P21/c.The neighboring Zn(Ⅱ) ions are linked by HL2-anions and Phen to form infinitely 1D zigzag chain,the 1D chains further linked each other to form 3-fold interpenetrated 2D wavelike sheet by H-bonding and π-πinteraction.In addition,the fluorescence property of 1 was also studied.CCDC:901345.
