Various combinations of mono- or diethynyl-substituted fluorene or carbazole building blocks were connected via a σ-bonded ethynyl linkage to ortho-metallated Pt(II) fragments, giving rise to phosphorescent mono- and dinuclear complexes for which the solubility and extent of delocalization could be tuned by the chemistry on the acidic methylene position of the fluorene.
