【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.更多还原

【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}{4³}₂{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.更多还原
