Metal–organic frameworks are coordination polymers composed of inorganic nodes connected by organic linkers. The 2-carboxyethyl(phenyl)phosphinic acid (CEPPA) is a ligand capable of bonding to a wide variety of metal ions. This review presents data concerning CEPPA and its metal complexes, along with a few examples of applications of the acid in combination with other compounds. It also highlights the synthesis and characterization of CEPPA.
