The unique optical properties exhibited by organic compounds with delocalized conjugated pi-electrons make these compounds ideal for fabricating a wide variety of optical and electro-optical devices. Moreover, the process for fabricating these materials into devices is relatively easy. Consequently, these factors have stimulated significant research into the integration of these materials into optical and electro-optical devices.
Still, despite substantial advances, researchers have yet to fully optimize devices employing these compounds. Specifically, problems persist physically among many of the organic materials currently used in optical and electro-optical devices. For example, many of the organic compounds used in these devices are difficult to synthesize. Likewise, other materials fail to provide optimal emissive or absorptive efficiency. Meanwhile still, other materials demonstrate less than ideal stability.
There is therefore a need to provide organic materials with improved optical properties.

Optical and Electro-Optical Devices (Absorbers/Emitters) – light emitting diodes, organic thin solar cells, dye-sensitized solar cells, organic concentrators, solar hydrogen generation, etc.

• Allows Tunable Absorption and Emission Profiles – varying the chemical structure of the ligand surrounding the metal center of these platinum complexes causes a predictable electronic structural response, allowing tunable absorption and emission profiles
• Improves Absorptive and Emissive Efficiency: greater than 37% efficiency achieved at room temperature
• Allows Both Absorptive and Emissive Capability in a Single Device
