A phase based approach to insulated molecular wires: Diplatinum octatetraynediyl complexes bearing fluorous trialkylphosphine ligands

When the sp chains of polyynes are lengthened, stabilities often decrease, and the title compounds are designed to “insulate” the wire like linkages with perfluoroalkyl groups, which show a marked tendency to phase separate from non-fluorous domains in solution and the solid state.211
