Exploration of superconductivity in polyparaphenylene oligomers

ORAL

Abstract

The appearance of superconductivity accompanied by some charge or spin order is the common feature for many unconventional superconductors. Suppressing such an order can bring about superconductivity in the systems such as cuprates, transition-metal dichalcogenides, and electron-transferred salts. We examine the case in polyparaphenylene oligomers. The birth of superconductivity in these molecules is indeed accompanied by the suppression of the charge order together with the formation of bipolarons. The latter can even exist at temperatures as high as 500 K. These findings open an encouraging window for the search of high temperature superconductors in chain link organic molecules.
