Electrodeless photoconductivity measurements of a rubrene single crystal are performed by microwave conductivity and transient optical spectroscopy, demonstrating anisotropy and ambipolarity. From these comprehensive studies, Akinori Saeki, Seiichi Tagawa, and co‐workers discuss on p. 920 the optoelectronic properties of rubrene single crystal in terms of charge recombination of holes and electrons, exciton–exciton annihilation, quantum efficiency of charge carrier generation, triplet contribution, and the extinction coefficients of ionic species accessed by pulse radiolysis.
