Abstract

Heterododecanuclear Pt₆Ln₆ (Ln = Nd, Yb) complexes of 4-ethynyl-2,2′-bipyridine (HC [triple bond, length as m-dash] Cbpy), prepared using emissive Pt(Me₃SiCCbpy)(CCbpy)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 Pt₂(dppm)₂(acetylide)₂ chromophores.
