The isolation and secondary functionalisation of the mer- and fac-isomers of tris(5-hydroxymethyl-2,2′-bipyridine) complexes of ruthenium (II)

Hydroxymethyl-functionalised 2,2′-bipyridine complexes of ruthenium complexes, and the corresponding aromatic esters have been separated into the geometrically isomerically pure forms and the respective photophysical properties investigated.
