hydrolyzed to the respective cyclopropenones. The unusually strong dipole moment associated with the cyclopropenone renders this core formally aromatic, an electronicstructure that becomes more important within individual monomers upon protonation of the carbonyl function with trifluoroacetic acid or alkylation with triethyloxonium salts. The electronic properties of cyclopropenone polymers in their pristine
