lanthanides - Opis:
- Macrocyclic complexes continue to attract considerable attention due to their significance in biological systems, catalysis, medical diagnostics and other fields. While the most intensively studied macrocycles containing donor nitrogen atoms are tetraazamacrocycles such as porphyrins or cyclen derivatives, larger macrocyclic ligands containing up to 18 (or even more) donor atoms are also known. Due to their enlarged size, these macrocycles can bind large metal ions such as lanthanide(III) ions or bind multiple metal ions. In this review a subclass of large macrocycles will be discussed i.e. macrocyclic amines and imines that can be generated in the condensation of diamines with dicarbonyl compounds, in particular with 2,6-diformylpyridine or 2,6-diformylphenols. These macrocycles of various sizes lead to a rich variety of structures of metal complexes, including polynuclear complexes. Moreover, macrocycles derived from enantiopure trans-1,2- diaminocylohexane form chiral metal complexes that exhibit unusual effects such as helicity inversion, enantioselective self-recognition or enantiodiscrimination of organic guest molecules.
