Solution Processable n-Type 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 easily synthesized n-type polymers and, subsequently, the lack of effective p-n junctions. Technology Description Professor Luscombe at the University of Washington has developed a synthetic route for the n-type polymer poly(benzimidazobenzophenanthroline ladder) (BBL) using soluble precursors. This synthesis allows for cheaper and more rapid production of BBL by ensuring that the entire process is soluble until the very end without disrupting the intermolecular
π-stacking that makes BBL so interesting and effective. Business Opportunity The ability to easily synthesize the n-type polymer BBL 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. Stage of Development A working methodology has been developed and characterized. Intellectual Property Position The UW is currently reviewing this technology for worldwide patent protection.
