Air-Stable p-Type Semiconducting Polymers

Introduction Conjugated polymers and organic semiconductors promise great advances in electronics because of the benefits they offer over silicon, including being cheaper with less demanding manufacturing requirements and allowing for larger, more flexible, and more robust materials that are more responsive to chemical and biochemical stimulus. A critical roadblock in developing this technology, however, is the lack of air-stable p-type polymers, for the cost of excluding oxygen during device fabrication has proven prohibitively high. Technology Description Professor Luscombe at the University of Washington has developed a series of polythiophene derivatives that are stable in air for over a year while maintaining their characteristically high charge mobility. These polymers greatly outlast the more conventional candidates, such as P3HT, which has an air stability of less than a day. Business Opportunity The ability to synthesize air-stable p-type polymers presents opportunities to advance the fields of electronics and photonics. There are immediate opportunities for the manufacture of a variety of components, such as light-emitting diodes, photovoltaic cells, and thin film transistors. Electroluminscence devices and solar cells are examples of the leading edge of technology that this methodology puts within our reach. Without the need to exclude oxygen from synthesis and fabrication, the cost and effort of creating effective organic semiconductors will drastically diminish. Stage of Development A working methodology for this technology has been developed and characterized. Intellectual Property Position The UW is currently reviewing this technology for worldwide patent protection.
