苯三羧酸锌配合物的水热合成、结构表征及发光性质研究

Polymeric Frameworks Constructed from Zn with Benzenetricarboxylic Acid Ligand Hydrothermal Synthesis,Crystal Structures and Luminescence

通过使用晶体设计规则,合成了新型的含有1,2,4-苯三羧酸和4,4’-联吡啶多齿混合配体的有机锌金属配位聚合物,并通过元素分析仪,红外光谱仪及X-射线单晶衍射仪对其结构进行表征,配合物展示了一个二维面状的超分子结构.在反应过程中,4,4’-联吡啶是作为后期进攻锌原子中心的二次配体,这在锌聚合物中是很罕见的,由于4,4’-联吡啶是一个线性分子,通常4,4’-联吡啶中的两个氮原子用来连接两个金属中心原子.配合物在紫外光照射下有较强的光致发光性质,探索了结构与性质之间的关系,为光敏材料的制备提供了实验支持及理论指导.

A novel metal-organic coordination polymers,[Zn（1,2,4-BTC）（bipy）]n（1,2,4-BTC = 1,2,4-benzenetricarboxylic acid,bipy=4,4＇-bipyridine） has been synthesized by using the principle of crystal engineering.The complex belongs to a 2-D plane structure.In this reaction,4,4＇-bipyridine acts as a terminal monodentate ligand to the Zn atom centers,which is rare in Zn polymers because 4,4＇-bipyridine is a linear molecule and it always bridges central ions using two nitrogen atoms.This coordination polymer shows blue luminescence in the solid state at room temperature.
