Abstract
A new, thermally stable conducting material, poly(3-amino-1H-pyrazole-4-carboxylate), can be used in a variety of applications such as thermoelectrics, electron acceptors in light-harvesting (photovoltaic) materials, and thermally stable conducting energetic materials. Related compounds include poly 3-amino-5-chloro-1H-pyrazole-4-carboxylate, poly 3-amino-5-bromo-1H-pyrazole-4-carboxylate, poly 3-amino-5-fluoro-1H-pyrazole-4-carboxylate, poly 3-amino-5-iodo-1H-pyrazole-4-carboxylate, poly 3, 5-diamino-1H-pyrazole-4-carboxylate, poly 3-amino-5-NHR1-1H-pyrazole-4-carboxylate, poly 3-amino-5-NR2-1H-pyrazole-4-carboxylate, or poly 3-amino-5-hydroxy-1H-pyrazole-4-carboxylate.
