|
Abstract:
制备了2个含3,4-二氯苯乙酸的锌和钡金属离子具有荧光性能发光材料，并采用X-射线单晶衍射、红外光谱及元素分析对其结构进行表征。配合物1为含锌化合物，配合物2为含钡化合物，两个配合物均为一维链状结构，结构单元之间通过C-H···O、C-H···Cl氢键作用组装成三维超分子网络结构。测试了两种配合物的紫外可见吸收和荧光性质。测试结果显示，两个配合物在不同溶剂中紫外可见吸收峰均在228 nm，不同溶剂中荧光发射峰均在546 nm，以及配合物1和配合物2的固态荧光发射峰分别在398 nm和452 nm。两种配合物可作为潜在的荧光材料。
Two fluorescent materials containing zinc and barium metal ions with 3,4-dichlorophenylacetic acid were synthesized and characterized by X-ray crystal diffraction, IR and elemental analysis. Complex 1 is a zinc-containing compound, and complex 2 is a barium-containing compound. Both complexes have a 1D chain structure. The structural units are interconnected via C-H···O and C-H···Cl hydrogen bonds to form a 3D supramolecular network. The UV-Vis absorption and fluorescence properties of both complexes were investigated. Experimental results indicate that the UV-Vis absorption peaks of both complexes in different solvents are centered at 228 nm, with fluorescence emission peaks observed at 546 nm in solution. The solid-state fluorescence emission peaks for complex 1 and complex 2 are located at 398 nm and 452 nm, respectively. These complexes demonstrate potential as optical materials.
