Two Anthracene-based Metal-Organic Frameworks for Highly Effective Photodegradation and Luminescent Detection in Water

Abstract

In this work, guided by the molecular building blocks (MBBs) strategy, anthracene-based linear organic ligand 4,4’-(9,10-anthracenediyl)dibenzoic acid (H2ADBA) is selected to synthesize two MOFs [(CH3)2NH2]2[Eu6(OH)8(ADBA)6(H2O)6]·(DMF)15 (Eu-ADBA) and [In3O(ADBA)3(H2O)3](NO3)·(H2O)6 (In-ADBA) by solvothermal reaction using modulator method. Eu-ADBA and In-ADBA which based on hexanuclear 12-connected and trinuclear 6-connected MBBs exhibit the classic fcu and acs topologies, respectively, and possess high thermostablility and water-stablility. Eu-ADBA performs broadly visible light absorption and highly photocatalytic activity for antibiotics tetracycline and organic dyes (rhodamine B and methylene blue) in water are tested, and the pore effect is further investigated. In-ADBA exhibits excellent fluorescence detective property for the antibiotics (nitrofurazone and nitrofurantoin) and nitroaromatics (2,4,6-trinitrophenol, 2,4-dinitrophenol and 4-nitrophenol) in water by quenching effect. This work presents the introduction of anthracene group into classical topological frameworks and reveals highly effective photocatalytic and detection abilities.
