Particular transition metal complexes exhibit interesting photophysical and semiconducting properties that can be utilized in electronic circuit components such as transistors and diodes, and in organic light emitting diodes (OLEDs) for general-purpose lighting and video displays. These components are ubiquitous and play an integral part in electronics that we use on a daily basis today including cell phones, HDTV's, and computers. Platinum(II) complexes designed in our group exhibit bright luminescence with high efficiency making them excellent candidates towards OLED applications. We have found that by varying the organic functionality of the ligands surrounding the Pt(II) center that we can achieve multiple emission colors as well as improve efficiency, attaining 100% under both optical excitation and electrical excitation at the device level. These materials also pack in a way that maximizes Pt-Pt overlap giving the material semiconducting behavior. The synthesis, characterization and photophysical properties of these complexes are reported, including nickel and palladium analogs that potentially will have similar characteristics and thus will help to further reduce cost.
