Polyaza-polyoxa

Multidentate polyaza and mixed polyaza-polyoxa macrocycles in their polyammonium form complex a variety of anions. Complexation ability is, as anticipated, related to macrocyclic ring size, macrocyclic topology and the relation of these factors to the substrate to be complexed. Polyammonium macromonocydes of various ring sizes and binding subunits complex polycarboxylate... 

Besides being used for the deprotection of amino acids and peptides, electrochemical cleavage has been employed in the synthesis of polyaza and polyaza-polyoxa ligands [259] the deprotection may be performed by direct as well as by indirect electrolysis. 

Interest in developing new lanthanide and actinide reagents has led to the synthesis of many new maeroeyclics derived from cyclic polyaza and mixed polyaza-polyoxa ligands (Biinzli and Wessner 1984, Bombieri 1987, Vallarino 1989), and from cyclic and open-chain polycatecholates (Raymond et al. 1984).
