目的:研究二维波浪形构型锌配合物的结构与荧光性质之间的关系,探究新型荧光材料的合成方法。方法:溶剂热条件下,硝酸锌与4,4’-二(苯并咪唑-1-甲基)联苯和4,4’-二羧基二苯基砜的自组装生成一个新型配合物[Zn(C14H18SO6)(C28H22N4)]n,并对配合物进行X-射线单晶衍射、热重分析、X-射线粉末衍射及固体荧光表征。结果:该配合物具有波浪形二维层状结构,且结构中苯并咪唑环之间存在强的π-π作用,使得该配合物在379 nm(激发波长为298 nm)处表现出优于配体的强荧光光谱。结论:合成了一种具有荧光性质的新型配合物,研究了配合物结构与性质之间的关系,为新型荧光配合物的设计合成提供参考。
Objective: To study the relationship between the structure and the fluorescence properties of two-dimensional wavy zinc complexes and to explore the synthesis method of new fluorescent materials. Methods: A novel complex of zinc nitrate with 4,4’-bis (benzimidazol-1-yl) biphenyl and 4,4’-dicarboxydiphenyl sulfone was prepared by solvothermal method [Zn (C14H18SO6) (C28H22N4)] n, and the complexes were characterized by single crystal X-ray diffraction, thermogravimetric analysis, X-ray powder diffraction and solid state fluorescence. Results: The complex has a wavy two-dimensional layered structure with a strong π-π interaction between the benzimidazole rings, which makes the complex show better performance at 379 nm (excitation wavelength of 298 nm) Strong fluorescence spectra of ligands. CONCLUSION: A new fluorescent complex has been synthesized and the relationship between the structure and properties of the complex has been studied. It provides a reference for the design and synthesis of novel fluorescent complexes.
