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。
In this paper, an interlocked two-dimensional coordination polymer {[Zn (BIDPE) (pim)) was synthesized by solvothermally using 4,4’-biimidazolyl diphenyl ether (BIDPE) and pimelic acid (H2pim) ] · (H2O)} n (1). Their properties were characterized by IR, TG, powder diffraction and single crystal diffraction. The complexes belong to the monoclinic space group P21 / c. Adjacent Zn 髤 ions form a chiral two-dimensional wavy surface by connecting BIDPE and pim2-, and two adjacent surfaces interlock with each other to form a 2Dchiral structure. 2Dchiral structures with adjacent interlocks have opposite helical directions, forming a 2Dachiral supramolecular framework by ABAB stacking. In addition, the fluorescence properties of the complexes were also studied.
