The ligand L8 is described by the authors as a podand, although the apical group is a polyazamacrocycle (51). The photophysical... [Pg.374]

Thus, it is the polyazamacrocyclic ligands developed by Lehn which have proved to be the most successful and versatile cryptands, rather than those carbon-bridgehead cryptands sought initially by Stoddart (25-27) which define a spheroidal cavity (e.g., 6). On the other hand, the bridged macrocyclic polyethers developed by Parsons (28), such as 7, show high complexing ability with alkali metal cations (28-30)... [Pg.4]

Several polyazamacrocycles have found applications in the field of medicine. The high thermodynamic and kinetic stability of their metal complexes, as well as the flexible coordination of these compounds towards very different metal ions, make them ideal candidates for in vivo applications. The complexes formed by such polyazamacrocycles remain intact, are not decomposed by trans-metallation with ligands present of biological fluids, and show a relatively good selectivity for metal ion binding. [Pg.806]

Many macrocyclic complexes of Ni (3d and Pd (4d are known. Polyazamacrocyclic ligands with methylated N-donor atoms form rather stable complexes with these metals. [Pg.211]

Macrocyclic systems—polyazamacrocycles. Anion complexation can only occur when over a certain range of pH the anion exists and the host ligand is in its protonated form. With the macropolycyclic systems previously described, this prerequisite for binding is obeyed for halide and azide guest anions. However, for the important classes of carboxylate and adenosine... [Pg.55]

The property of a number of macrocyclic ligands, primarily polyazamacrocycles with unsaturated cyclic backbones, to give coloured compounds with metal ions. [Pg.541]
