Abstract
Derivatives of 1,10-phenanthroline and their metal complexes are of considerable interest in bioinorganic chemistry, biology and medicine.1 In this nexus, dendritic modification gain in importance as they open the way for tailoring nano dimension, and solubility or complexation behaviour.2 We described hydrophobic oxybathophenanthroline ligands with attached Frechet-type dendrons capable of forming stable copper(II) complexes in organic media.3 Currently, effort is also to be devoted to the synthesis of hydrophilic 4,7-diphenyl-1,10-phenanthroline ligands LG1 LG3 containing short methoxypolyethoxy (PEG) groups on the surface. Radiotracer experiments using 64Cu and time-resolved laser-induced spectroscopy point to a spontaneous formation of stable 1:2 complexes (metal:ligand) with copper(II) in aqueous solution.
