High temperature superconductivity in K-doped 1,2:8,9-dibenzenopentacene (C₃₀H₁₈) has been recently reported with T_c = 33 K, the highest among organic superconductors at ambient pressure. Here we report on our search for superconductivity in K, Ba, and Ca-doped hydrocarbon organic materials. We find that Ba-anthracene (C₁₄H₁₀) and K-Picene (C₂₂H₁₄) show features characteristics of superconducting state, although very weak. Furthermore, the data suggests that Ba-anthracene might be a new organic superconductor with T_c ~35 K.
