Abstract
Starting from 4,7-dichlorophenanthroline (1) a synthetic approach is develo ped to novel macrocyclic mono- and bisphenanthrolines (5a-d, 6a-d) with exo topic binding sites. As these coordinating compounds are characterized by a flexible spacer unit, their utility as ligand for the construction of olig omeric, dendritic and box-like structures in the presence of copper(I) and iron(II) is evaluated. Spectroscopic data suggest that with copper(I) the [ 1+1] adduct [CU2(6C)(7)](2+) is formed.
