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(英文)

Structure and Photoluminescent Property of Three-Fold Interpenetrated 2D Zn(Ⅱ) Coordination Polymer Induced by H-Bonding and π-π Interaction

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 monoclinie 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 interaction. In addition, the fluorescence property 3-fold interpenetrated 2D wavelike sheet by H-bonding and or-or of 1 was also studied. CCDC： 901345.
