Design Strategies of Metal Complexes Based on Chelating Polymer Ligands and Their Application in Nanomaterials Science

The advances and problems associated with the synthesis, properties and structure of metal complexes based on chelating polymer ligands are presented and assessed. The polymeric metal chelates (PMCs) are divided into molecular, intracomplex, macrocyclic and polynuclear types, which in turn are grouped according to the nature of the donor atoms (N,N-, N,D-, N,S-, D,D-, O,S-, S,S-, D ,D -chelates, etc.). The main attention is focused on the similarities and differences between low and high molecular weight metal chelates, as well as the spatial organization of PMCs. The most important areas of research in the field of such compounds are highlighted. Thermal transformations of metal complexes based on chelating polymer ligands leading to the formation of nanostructured materials are considered. The bibliography includes the articles published after 2010.
