Molecular structure design and soft template synthesis of aza-, oxaaza- and thiaazamacrocyclic metal chelates in the gelatin matrix

The data about of soft template synthesis proceeding in gelatin matrices in [3d-element M(II) ion - (N, S)-or (N, O, S)-ambidentate ligson - mono- or dicarbonyl ligson] systems, have been considered and discussed. The chemical nature of the final products of template synthesis formed under these specific conditions, has been compared with the chemical nature of the final products formed by template synthesis in solutions. It has been noted that in many cases, the nature and chemical composition of these products differ substantially. Specific features of the DFT calculated molecular structures of the macrocyclic compounds that can be formed due to the template synthesis in the systems indicated above, have been discussed, too. The review covers the period 1990-2015. (C) 2016 The Author. Production and hosting by Elsevier B.V. on behalf of King Saud University.
