Heterododecanuclear Pt(6)Ln(6) (Ln = Nd, Yb) arrays of 4-ethynyl-2,2 '-bipyridine with sensitized near-IR lanthanide luminescence by Pt -> Ln energy transfer

Heterododecanuclear Pt(6)Ln(6) (Ln = Nd, Yb) complexes of 4-ethynyl-2,2'-bipyridine (HC=Cbpy), prepared using emissive Pt(Me3SiC=Cbpy)(C=Cbpy)(2) as an alkynyl bridging ligand'', afford sensitized near-infrared (NIR) lanthanide luminescence by Pt -> Ln energy transfer from both Pt(bpy)(acetylide)(2) and Pt-2(dppm)(2)(acetylide)(2) chromophores.
