Structural, photophysical and -chemical characterisation and reactivity of a novel polypyridyl
ruthenium complex based on 3,5,6,8-tetra-bromophenanthroline are discussed.
Signal storage at a molecular level is great challenge for chemistry.1 The possibility of
connecting different functionalities selectively to one ligand of a metal complex may open the
route towards higher integrated molecular units capable of processing various external stimuli
in a predesignated order. The implementation of this concept demands ligands with a
multitude of potential connecting groups which can selectively be transformed.2 3-bromo- and
3,8-dibromophenanthrolines have proved useful for the preparation of mononuclear3 and
multiheteronuclear complexes.4 These systems have found applications ranging from DNA
photoprobes5 to metalloligands in catalysis.6 A very useful feature of this
bromophenanthroline ruthenium complexes is their susceptibility towards nucleophilic
aromatic substitution which is very well established.
