A renewed interest on organic superconductivity has emerged after the recent observation of a Meissner effect in K-doped p-terphenyl at temperatures as high as the ones of the high temperature superconducting cuprates.  Even if there is still a strong debate about the actual superconducting transition temperature and the various electronic and structural transformations taking place in this family of compounds, different groups have reported by now superconductivity in K-doped p-terphenyl or other polyphenyls. This discovery raises lots of questions on, similarly to the fullerides, the role ​of strong electronic correlation​s,​ as well as of a polaronic component and of the possible mechanisms driving the formation of a complex superconducting phase in enhancing the superconducting transition temperature:, multiple condensates, symmetry of the condensates, condensates in the BEC or BEC-BCS crossover regime and Fano resonances. The aim of this topical issue is to provide a broad overview on the experimental and theoretical research activity done over last two years by various research groups on superconductivity in doped p-trephnyl, along with the most recent advancements.  Not only K doped p-terphenyl but also other related families of organic superconductors will be included in this special issue of Novel Superconducting Materials.
