Patent number: 11920035Abstract: This disclosure concerns electrically conducting poly(pyrazoles). The concept of oligomerizing and polymerizing substituted aminopyrazole derivatives combined with a monomer activation procedure involving base-mediated conversion of the protonated pyrazole ring nitrogen to amine salt was developed. This disclosure concerns the specific chemistries needed for the synthesis of a pyrazole monomer used in the polymer synthesis. The procedure used for blending the novel polypyrazoles with other compounds needed for construction of solar cells for testing was developed. This disclosure concerns the concept of using these types of heteroatom-rich, electron-deficient oligomers or polymers as n-dopable or p-dopable electron acceptors in photovoltaic cells. This disclosure concerns synthesizing the starting monomer compounds and polypyrazoles.Type: GrantFiled: October 25, 2022Date of Patent: March 5, 2024Assignee: The Government of the United States of America, as represented by the Secretary of the NavyInventors: Brett D. Martin, Ian D. Giles, Jawad Naciri, Paul T. Charles, Scott A. Trammell, Jeffrey R. Deschamps, Jeffrey C. Depriest
