 I shall talk about the new carbonhydron superconductors : alkali-, alkali earth and rare earth metals doped phenanthrene, and give you evidences for possible unconventional superconducitivty  in such organic superconductors.We characterized the doped Phenanthrene by XRD, Raman spctroscopy and Susceptibility. The Raman scpetra show 7 cm^-1 per electron downshifts generated by charge transfer from dopants to molecules. The shielding fraction of Ba1.5Phenanthrene is about 100%, indicating a model system for studying the intrinsic physical properties and superconductivity mechanism in these organic π-molecular materials. We measurd the spcific heat of Ba1.5Phenanthrene  and discussed the superconduting pairing symmetry  in this newly found  organic superconductors.
