Superconductivity in K-doped <i>p</i>-quinquephenyl

ORAL

Abstract

The chain-like organic compounds with conjugated structure have the potential to become high temperature superconductors. P-Quinquephenyl with five benzene rings connected in para positions is found to exhibit superconductivity at a critical transition temperature of 7.3 K. The dc and ac magnetic measurements reveal the Messiner effect and the realization of superconducting state. The occurrence of bipolarons discovered by Raman spectra guarantees potassium metal intercalated into p-quinquephenyl. X-ray diffraction patterns indicate the doped samples are poorly crystallized.
