Study on Fluorescence Sensing of 2D Calcium Metal-Organic Frameworks to Tetracycline Hydrochloride

Detection methods based on changes in fluorescence intensity have been widely studied because of their convenience, fast response, and high sensitivity. In many fluorescent materials, luminescent metal-organic frameworks(LMOF) exhibit the characteristics of simple preparation and recyclability, which has become a new type of detection material. Thus, a two-dimensional structure is prepared by combining amide functionalization ligand with alkaline earth metal calcium (namely CUST-620), not only the fluorescent intensity is improved, but also the thermal stability is ideal. The excellent luminescence properties and fluorescent sensing of antibiotics are commonly used in aqueous environments. The results present significant quenching occurring when tetracycline hydrochloride is added to CUST-620. It is expected to become a novel antibiotic fluorescent sensor.
