氢键和π-π诱导的二维双层Zn(Ⅱ)配位聚合物的晶体结构和荧光性能(英文)

Structure and Fluorescence Property of 2D Bilayer Zn(Ⅱ) Coordination Polymer Induced by H-Bonding and π-π Interaction

本文以间苯二吡啶(1,3-dpb)和4,4′-二苯醚二甲酸(H2oba)为配体,溶剂热合成了一个二维锌配位聚合物{[Zn(oba)(dpb)].H2O}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C2/c。相邻的Zn(Ⅱ)离子通过连接oba2-和dpb形成二维波浪形面,两个相邻的面相互互锁形成2D→2D的结构,并且面与面之间存在氢键。两组2D→2D的结构通过π-π作用进一步形成双层的二维超分子网络。此外,本文也研究了配合物的荧光性能。

Solvothermal reaction of 1,3-dipyridyl benzene （1,3-dpb） with 4,4＇-oxybis（benzoic acid） （H2oba） produced a two dimensional （2D） zinc（Ⅱ） coordination polymer {[Zn（oba）（dpb）]·H2O}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 C2/c. The neighboring Zn（Ⅱ） ions are linked by oba2- anions and 1,3-dpb to form infinitely 2D sheet, two 2D sheets are interlocked each other to form 2D→2D structure, and these two 2D sheets were linked each other by H-bonding. Two groups of interlocked structures further linked to form bilayer 2D supermolecule network by π-π interaction. In addition, the fluorescence property of 1 was also studied. CCDC： 917714.
