Covalent surface confinement of osmium–terpyridine complexes: a UV–VIS and XPS study
Abstract
Well defined monolayers of –Si(CH2)4Ph–tpy–OsCl3, –Si(CH2)4Ph–tpy–Os(tpy) and –Si(CH2)4Ph–tpyOsCl– (PPh2)2CCC(PPh2)2–Os(bpy)2 (tpy = 2,2′:6′,2″-terpyridine, bpy = 2,2′-bipyridine) on polycrystalline quartz surfaces are prepared and studied by UV–VIS and X-ray photoelectron spectroscopy.
