Abstract

Metal organic frameworks (MOFs) are gaining interest for technological purposes due to their intriguing open structure properties such as ion exchange, catalytic properties and application as sensors. To prepare coordination compounds with desired properties, the choice of organic ligand is crucial. This work demonstrates the hydrothermal synthesis of a copper(II) coordination compound with 2-hydroxynicotinic acid. Characterization was based on elemental analyses, ESI-MS, MALDI-TOFMS, FT-IR spectra, thermogravimetric analysis (TGA), and cyclic voltammetry. Electrochemical characterization of the compound prepared was also carried out to find a sensitive and simple method to improve the determination of biologically active thiol substances. From the rectangular voltammetry results, a linear response between 0.2 and 20 μM was obtained with an estimated detection limit of 0.09 μM.
