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
