A novel phosphorescent cyclometalated platinum dimer with bis-[2-(p-dodecyloxyphenyl) pyridyl]-hexane-l,6-diol as ligand and 1,3-( 1-n-hexyl,3-n-heptadecyl) diketone as ancillary ligand was synthesized. The chemical structure and liquid crystal property of the dimer were characterized by ¹H NMR, ESI-MS, polarizing optical microscopy (POM) and differential scanning calorimetry (DSC). The aligned film of title compound on the rubbed polyimide film is intensely emissive at room temperature with emission maximum at 516 nm. The luminescence dichroic ratio (I_∥/I_⊥) at 516 nm is 3.1.
