The preparation of RuL(3) (1), RuL(2)L' (2) and Ru(pod) (3) complexes
containing polyethylene glycol chains is described. The complexes are
further functionalized by 4-oxyanisyl or by hydrophilic hydroxyl group
s. These new complexes may interact in supramolecular assemblies with
suitable accepters such as mono- and bisviologens to form biomimetic m
odels for photosynthesis.
