Soluble Oligoimide Molecular Lines Which Have Persistent Poly(anion radicals) andPoly(dianions)

摘要

Recent work from this laboratory has demonstrated the unusual properties of'molecular lines'; rigid rod molecules with defined lengths in the nm range. It has been shown that these compounds which are typically polyacene quinones form organized monolayers, can be imaged using STEM, and form stable anions. The long wavelengths absorption bands and high conductivity of simple salts of these anions are of considerable interest and suggest that some of the anions can be considered to have mixed valence. Another laboratory has reported molecular rods in which bicyclobutane groups were used to form small oligomers. We also draw attention to rigid, aliphatic spacers used to study electron transfer rates.
