    Reactions between 3,4-propylenedioxythiophenes (ProDOTs) and N-alkyl isatins under ambient conditions result in isomerically pure indophenine materials as confirmed by TLC and 1H NMR analysis. The resulting low band gap materials exhibit favorable inter- A nd intramolecular interactions, high thermal stabilities, low energy electronic transitions, and amphoteric redox behavior.
