Solvothermal Preparation

Metal-organic frameworks (MOFs) have been rapidly developed for their broad applications in many different chemistry and materials fields. In this work, a multi-dentate building block 5-(4-(tetrazol-5-yl)phenyl)-isophthalic acid (H3L) containing tetrazole and carbolxylate moieties was employed for the synthesis of a two-dimensional (2D) lanthanide MOF [La(HL)(DMF)2(NO3)] (DMF = N,N-dimethylformamide) (1) under solvothermal condition. The fluorescent sensing application of 1 was investigated. 1 exhibits high sensitivity recognition for antibiotic nitrofurantoin (Ksv: 3.0 × 103 M−1 and detection limit: 17.0 μM) and amino acid l-tyrosine (Ksv: 1.4 × 104 M−1 and detection limit: 3.6 μM). This work provides a feasible detection platform of 2D MOFs for highly sensitive discrimination of antibiotics and amino acids.

Abstract A novel porous Cd(ii) metal–organic framework (MOF) with the chemical composition of {[H3O][Cd(bci)]} n ·2n(H2O) (1, H3bci = bis(2-carboxyethyl)isocyanurate) was prepared via hydrothermal responses of H3bci and Cd(NO3)2·4H2O. Luminescent property investigations indicated that compound 1 had high sensitivity toward Fe3+, and the detection limit of Fe3+ was as low as 2.15 × 10−4 M. The application values of Fe3+ on Hepatitis B were assessed, and its associated mechanism was identified simultaneously. First, the cytotoxic mediator (TNF-α) substance released into plasma was measured through the ELISA. In addition, real-time RT-PCR was employed to determine the Hepatitis B viral replication gene relative expression levels. Finally, the novel compound’s toxicity against human normal liver cells was tested by using the CCK-8 assay.
