摘要:

以柔性1,5-双(2-乙基苯并咪唑)戊烷(简称bep)为主配体,在1,3-金刚烷二乙酸(简称H2 ada)的调控下,通过与Zn2+进行自组装反应,合成了一种新颖的配合物材料{[Zn2(bep)(ada)22H2O}n.单晶X-射线衍射分析表明该配合物材料为二维层状结构;完全失质子的金刚烷二乙酸离子采用单齿和螯合的双重配位模式连接Zn1和Zn2,构成一维双链结构;1,5-双(2-乙基苯并咪唑)戊烷采取反式构象将一维双链拓展成二维层.该配合物材料在280 ℃仍保持骨架完整,具有良好的热稳定性;配合物在激发波长285 nm下,在309 nm处显示了较强的荧光发射峰,可作为潜在的荧光材料.

关键词: 配位聚合物, 自组装, 热稳定性, 荧光

Abstract:

A zinc coordination complex {[Zn2(bep)(ada)2] 2H2O}n has been synthesized based on a flexible ligand 1,5-bis(2-ethylbenzimidazole) pentane (bep) and 1,3-adamantanediacetic acid (H2 ada).Single-crystal x-ray diffraction showed that the complex was a two-dimensional layered structure.Ada2- taked the monodentated and chelating coordination modes,linking Zn1 and Zn2 to form a one-dimensional double chain.Then the chains were further linked by the bep ligand to form the two-dimensional layered structure.In addition,the thermal stability and fluorescence property of the complex were also investigated.

Key words: coordination complex, self-assembly, thermal stability, fluorescence property
