Abstract

We report the observation of superconductivity at 33 K in K-doped 1,2:8,9-dibenzopentacene (C30H18). This is higher than any Tc reported previously for an organic superconductor besides the alkali-metal doped C60. This finding provides an indication that superconductivity at much higher temperature may be possible in such system, if PAHs with longer benzene rings can be synthesized.
