Research Abstract

We suggest more general theory than the BCS theory in order to elucidate the relationships between the intramolecular diamagnetic supercurrents at 298 K in microscopic sized π-conjugated hydrocarbons such as benzene and polyacenes and the conventional superconductivity at low temperatures in bulk systems [1], which have not been elucidated for about 100 years. According to our calculations, intramolecular diamagnetic supercurrents in microscopic sized π-conjugated hydrocarbons are induced by electron pairing as a consequence of Coulomb interactions (electron-phonon interactions can be neglected).
