摘要:

采用1,2,3-三羧基-(1′,2′,3′-三羧基偶氮苯)-苯(H6TTAB)连接线性四核铕配位单元, 组装形成具有 {414·620·811}{43}2{45·6}拓扑结构的稀土金属-有机框架Eu-TTAB. Eu-TTAB具有高的热和溶剂稳定性, 在紫外光激发下具有发光性质, 且其发光性能可以被铽离子调控并被银离子大幅度提升.

关键词: 稀土, 金属-有机框架, 发光性质

Abstract:

A rare earth metal-organic framework(MOF), Eu-TTAB, formed by the coordination of 1,2,3-tricarboxyl-(1′,2′,3′-tricarboxylazophenyl)-benzene(H6TTAB) and linear tetranuclear europium coordination unit, with a {414·620·811}{432{45·6} topology, was synthesized by hydrothermal method. Eu-TTAB showed excellent thermal stability and solvent stability. Flourescence property of Eu-TTAB under UV excitation was studied. Furthermore, the fluorescence of Eu-TTAB can be tuned by terbium ions as the second emission center and silver ions to enhance the luminescence intensities.

Key words: Rare earth, Metal-organic framework, Fluorescence property
