Soluble Tetrahedral Compounds for use in Electroluminescent Devices
BACKGROUND: Recent research efforts have produced stable amorphous materials that can be cast into films directly from solution. However, a tendency towards crystallization minimizes the utility of these materials as the electroluminescent layer in light emitting diodes (LEDs). Attempts to use these materials as the emissive component for organic LEDs were discouraged because the restricted conjugation length would potentially inhibit efficient charge transport.
DESCRIPTION: Scientists at the University of California have developed a novel class of soluble tetrahedral molecules of intermediate dimensions that can be used to fabricate efficient organic LEDs.
APPLICATIONS: This new UC invention has applications in fabrication of organic LEDs for electroluminescent devices.
ADVANTAGES: The new UC technology provides the following benefits:
* Increased stability in the amorphous structure improves the material's film-forming ability;
* Allows fabrication of organic LEDs with low turn-on voltages;
