Osmium complexes bearing functional groups: Building blocks for integrated chemical systems
Two new redox-active osmium complexes of the type (Os(bpy)2Cl(pyX))+ have been synthesised, where pyX corresponds to a pyridine derivative bearing a functional group (aldehyde, carboxylate). Their electrochemical behaviour and electronic spectra were studied in acetonitrile and aqueous solutions. Th...
