Effective Method for Synthesizing Polysiloles and Polygermoles


Robert West, Yuxia Liu, Honglae Sohn

The Wisconsin Alumni Research Foundation (WARF) is seeking commercial partners interested in developing a method to synthesize polysiloles and polygermoles that have improved electrical properties.
OVERVIEWSiloles and germoles are compounds that are of considerable commercial interest because of their unusual electronic properties. It has been proposed that they be used for electro-transporting materials and as light-emitting diodes; however, attempts at synthesizing these compounds have resulted in undesirable film-forming properties and the desired electrical properties such as fluorescence, electroluminescence or semiconducting have not been achieved. Additional compounds that possess these desired electrical properties are needed.
THE INVENTIONUW–Madison researchers have developed more efficient methods of synthesizing polysilole and polygermole compounds. The silicon or germanium ring atoms from each polymer unit are directly linked to one another to achieve the important electrical properties of fluorescence and electroluminescence.
  • Organic transistors where electron transporting materials are desired
  • Single compound LEDs for flat panel displays
  • Polysiloles, polygermoles and silole-germole copolymers
  • More efficient production
  • Improved electrical properties
