The synthesis of a novel trifunctional Pt(II) cyclometalated complex in which the hole-transporting (HT), electron-transporting (ET), and electroluminescent (EL) components are integrated into a single molecule is accomplished, and this complex can be sublimed and used for the fabrication of neat emissive layer electro-phosphorescent devices.

The synthesis, structural, photophysical, electrochemical and electroluminescent properties of a novel class of bifunctional molecule are reported in which the hole-transporting triarylamine and electron-transporting oxadiazole components were combined. The strongly luminescent compounds displayed good thermal and morphological stability as well as intense fluorescence both in solution and thin film

are integrated into a single molecule. These neutral metal chelates display good thermal stability (>250 degrees C under N2) and morphological stability. All of them exhibit intense ligand-centered fluorescence and phosphorescence in fluid solutions at room temperature, but the emission spectra become largely dominated by triplet emission bands in CH2Cl2 glass at 77 K.
