Phosphazene-Containing Ligands and Complexes on Their Base

Аннотация

Recent developments in the synthesis of phosphazene-based ligands (preparation of polyfunctional coordination ligands such as pyridyloxy-, pyrazolyl-, phenanthroline-, porphyrine-, carboxyl-, fluorene-, 1,1'-bis-2-naphthol-, coumarin-, and oxazoline-containing cyclophosphazenes as well as phosphazenes containing crown ether and spirocyclic groups) are reviewed. Coordination behavior, complex formation properties, and certain peculiar features of these ligands are described. Special attention is paid to their applications in science and technology.
