Abstract
Heterododecanuclear Pt(6)Ln(6) (Ln = Nd, Yb) complexes of 4-ethynyl-2,2'-bipyridine (HC[triple bond, length as m-dash]Cbpy), prepared using emissive Pt(Me(3)SiC[triple bond, length as m-dash]Cbpy)(C[triple bond, length as m-dash]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.
