The review article summarizes and systematizes many years of literature data on possible areas of application of aminocarboxyphosphonic acids and metal complexes based on them. It is shown that aminocarboxyphosphonates, due to their wide range of functional properties, in particular, such as photoluminescence, magnetic properties, biological activity, can find application in a wide variety of areas. Both aminocarboxyphosphonic acids themselves and their complexes can serve as the basis for biologically active substances in agronomy - as synthetic growth regulators, as effective preparations for increasing extracted sugar from various plants (sugar cane, sweet potato, sugar beet, melon, etc.) and preparations for accelerating fruit ripening under adverse weather conditions. One of the most interesting areas of use of aminocarboxyphosphonates and nanoparticles based on them for biomedical purposes is the creation of precursors for the development of new antitumor drugs. Due to their high poro­sity, these materials can be used in ecology for the purification of soil and/or drinking water from heavy metals. The approaches to the modification of the coordination environment, variations in the nature of metals and ligand environment highlighted in the work can be used as a model for the development of new coordination polymers and MOFs structures as environmentally friendly depressants for selective flotation separation of minerals (dolomite, galena, sphalerite). Aminocarboxyphosphonates of metals as a subclass of coordination po­lymers, due to the presence of such groups in the molecules as POH, COOH, N+-H, demonstrate acidic properties, the combination of which with electrocatalytically active transition metals makes them very attractive in the field of fuel cells and electrolyzers. They can be used as potential proton conductors and/or precursors of electrocatalysts, heterogeneous catalysts in the Knoevenagel condensation with high selectivity.
