Abstract

Incorporation of diplatinum complex Pt2(μ-dppm)2(bpyC[triple bond, length as m-dash]C)4 or Pt2(μ-dppm)2(phenC[triple bond, length as m-dash]C)4 with Ln(hfac)3(H2O)2 (Ln = Nd, Eu, Yb) gave a series of Pt2Ln2 and Pt2Ln4 bimetallic arrays, in which the excitation of d(Pt) → π*(R–C[triple bond, length as m-dash]C) MLCT absorption induces sensitisation of lanthanide luminescence through efficient d → f energy transfer from PtII alkynyl chromophores.
