Preparation and Characterization of Nitrogen and Oxygen Containing Graphite-lke Pyropolymers from 5-(2-Pyridyl)-2,4-pentadiyne-1-ol

Abstract

5-(2-Pyridyl)-2,4-pentadiyn-1-ol was polymerized over NbCl5- or TaCl5-based catalysts followed by pyrolysis to obtain graphite-like pyropolymers. The black metathesis polymer, poly[5-(2-pyridyl)-2,4-pentadiyn-1-ol], has the structure of a fully conjugated backbone and was converted into a polyacene-based polymer having pyridyl pendant groups. The pyropolymers prepared by vacuum pyrolysis over 700 degrees C have nitrogen atoms incorporated into graphene sheets. The polymers were characterized by elemental analysis, TGA, FT-IR, laser Raman, NMR, XPS, X-ray diffraction, temperature-programmed desorption experiments, charge/discharge experiments, and SEM and TEM studies.
