•A novel ligand was prepared and characterized.•A novel three-dimensional europium metal-organic framework was structurally characterized.•The compound can detect Al3 + ion quickly with high sensitivity and selectivity. Additionally, a self-made fluorescence test paper was also fabricated.•The compound displays high thermal and solvent stability.
A novel three-dimensional europium metal-organic framework (Eu-MOF), [Eu(L)(OAc)(DMA)]n (1), has been successfully obtained based on a newly designed ligand 4′-(3,5-dicarboxyphenyl)-4,2′:6′,4″-terpyridine (H2L). The structure of 1 was established by single crystal X-ray diffraction technique, and structure analysis shows that two Eu3 + in 1 are 4-fold bridged by two η1:η1:μ2 carboxylates from L2 − and the other two η1:η2:μ2 carboxylates from acetic acid, respectively. The binuclear [Eu2] were further linked by L2 − to form a 3D framework. The investigations on luminescent properties reveal that 1 can detect Al3 + quickly with relatively high sensitivity and selectivity. More importantly, it displays high thermal and solvent stability. Additionally, a self-made fluorescence test paper fabricated based on 1 was used to detect Al3 + in practice.
