SYNTHESIS AND STRUCTURE OF 2,3-DIHYDROXYL-5-CARBOXYLBENZENESULFONIC ACID SUPRAMOLECULAR COMPLEX WITH HEXA-AQUA COBALT COMPLEX

The novel arenesulfonic acid, featuring three functional groups – carboxyl (–CO₂H), sulfonic acid (–SO₃H), and hydroxyl (–OH) – specifically 2,3-dihydroxy-5-carboxybenzenesulfonic acid, was synthesized by Ge et al. in 2018 [1]. The goal of this synthesis was to develop lithium(I)-based metal-organic frameworks (MOFs) with potential applications in areas such as photochemistry, electrochemistry, sensors, catalysis, and especially in gas storage and small molecule separations.
