V 型咪唑配体构筑的二维穿插层状锌Ⅱ配合物的晶体结构及荧光性能(英文)

Structure and Fluorescence Property of 2D Interlocked Zn(Ⅱ) Coordination Polymer Constructed by V-Shaped Imidazolyl Ligand

本文以4,4′-二咪唑基二苯醚(BIDPE)和庚二酸(H2pim)为配体,溶剂热合成了一个互锁的二维配位聚合物{[Zn(BIDPE)(pim)]·(H2O)}n(1)。对其进行了红外、热重、粉晶衍射、单晶衍射等表征,配合物属于单斜晶系,空间群P21/c。相邻的Zn髤离子通过连接BIDPE和pim2-形成手性二维波浪形面,两个相邻的面相互互锁仍然形成2Dchiral的结构。相邻互锁的2Dchiral结构的螺旋方向相反,通过ABAB堆积最终形成了2Dachiral超分子框架。此外,本文也研究了配合物的荧光性能。

A new interlocked 2Dachiral coordination polymers {[Zn（BIDPE）（pim）]·（H2O）}n （1） was prepared under hydrothermal conditions based on V-shaped ligand 4,4＇-bis（imidazol-1-yl）diphenyl ether （BIDPE） with aliphatic pimelic acid （H2pim）. The complex was characterized by IR spectroscopy, TGA, X-ray powder and single-crystal diffraction. It crystallizes in the monoclinic system, space group P21/c. The neighboring Zn（Ⅱ） ions are linked by BIDPE and pim2-anions to form infinitely 2Dchiral layer, two identical 2Dchiral layers interlocked each other to give 2Dchiral＋2Dchiral→2Dchiral sheet. The helical directions of adjacent interlocked 2Dchiral sheets are reverse, which stacked in ABAB mode to form 2Dachiral network. In addition, the solid-state photoluminescent property of 1 was also studied. CCDC： 933583.
