Cyclometallated platinum(II) complexes incorporating ethynyl-flavone ligands: switching between triplet and singlet emission induced by selective binding of Pb2+ ions

Platinum-ethynylflavone complexes featuring various polyether arms display 3IL phosphorescence associated with the appended flavone perturbed by the platinum centre (tau approximately 20 micros), but switch dramatically to flavone-localised 1IL fluorescence (tau approximately 2 ns) upon selective bi...
