Notes:
Through electrical conductivity and ESR measurements of heat treated BBB-rigid-rod ladder polymers, we provide evidence for the existence of an irreversible transformation to another cross-linked ladder polymer with high intrinsic conductivity. The transformation occurs at a pyrolysis temperature, Tp ≅ 680°C. The results suggest a novel transport mechanism.
