Superconductivity in K-doped triphenylamine

Organic compounds especially which with π-electron are promising candidates to exhibit high temperature or even room temperature superconductivity. Triphenylamine is a fundamental materials in Organic Light Emitting Diode (OLED) which with special electronic transport in the molecules. We successfully synthesized potassium-doped triphenylamin. Superconductivity was found in this material at a critical temperature of 7 K. We obtained the superconductive parameters such as the critical fields, penetration depth and Ginzburg-Landau coherence length for this superconductor. This finding open an encouraging window for the search of superconductors in aniline compounds.
