Polypyrrole (PPy) is of great potential importance due to its excellent conductive properties; however, a major obstacle to commercialization (like many synthetic metals) is its poor stability, especially to oxidation. Here is reported a new synthesis of PPy in the presence of the cobaltabisdicarbollide anion (see Figure), whose uniform distribution throughout the polymer leads to a dramatic improvement in the overoxidation threshold.
