Value Proposition
· Flexibility to be combined with various n-type conductive materials
· Faster manufacturing capability: The ability to create and implement dopants for organic conductants at broader scale.
Unmet Need
· Organic conductants are used in a variable of applications, such as organic field- effect transistors, solar cells, and organic light-emitting diodes. They consist of a conductant and a dopant, which allow for the transportation of positive and negative charges (Pei, 2022). Modern dopants can be difficult to effectively combine with organic semiconductors. Thus, there exists a strong need for developing a more flexible, organic dopant to address this limitation.
Technology Description
· Current methods for producing organic conductant dopants do not allow for polymeric dopants. Researchers at Johns Hopkins have developed a organic conducting polymer that itself can be doped with polymeric dopant molecules. Work demonstrates that this product is more soluble, conductive, and stable compared to current doping methods.
Stage of Development
· Benchtop proof of concept has been demonstrated.
· Current efforts focus on finalizing compositions of the polymer and the scale of the production process.
Data Availability
· Data available upon request.
