| Abstract | The mol. wt., thermal stability, and cond. of chem. synthesized, self-doped poly(aniline boronic acid) have been detd. Gel permeation chromatog. results indicate a no.-av. mol. wt. of 1,676,000 g mol-1, a wt.-av. mol. wt. of 1,760,000 g mol-1, and a polydispersity of ∼1.05. The high mol. wt. is maintained following removal of boronic acid groups via ipso-substitution reactions, suggesting that boronic ester cross-links do not contribute significantly to the high mol. wt. obsd. According to thermogravimetric anal. results, the thermal stability of self-doped poly(aniline boronic acid) is greater than that of HCl-doped polyaniline and other self-doped forms of polyaniline. Unlike polyaniline, which experiences complete decompn. of the backbone above 400 °C, self-doped poly(aniline boronic acid) remains largely intact and possesses cond. near 0.01 S cm-1.
