Ligand loss photochemistry in copolymerized films of poly-cis-[Ru(Me[sub 4]bpy)[sub 2](vpy)[sub 2]][sup 2+][Os(vbpy)[sub 3]][sup 2+] (Me[sub 4]bpy is 4,4[prime],5,5[prime]-tetramethyl-2,2[prime]-bipyridine, vpy is 4-vinylpyridine, vbpy is 4-methyl-4[prime]-vinyl-2,2[prime]-bipyridine) on Pt electrodes results in loss of [-Ru(Me[sub 4]bpy)[sub 2]][sup 2+] and the creation of molecular voids. The vpy binding sites in the poly[Os(vbpy)[sub 3]][sup 2+],vpy films which remained were used to coordinate [-Os(PMe[sub 2]Ph)[sub 3]Cl[sub 2]] following reduction of mer-Os(PMe[sub 2]Ph)[sub 3]Cl[sub 3] at the underlying electrode. By using masking techniques, it was possible to incorportae the Os[sup II] complex with spatial control. 15 refs., 4 figs., 1 tab.
