Organic radicals have been attracted much attention from the viewpoints of not only synthetic chemistry but also materials science. Longer-wavelength absorptions and emissions, and reversible redox properties are of the typical advantages of organic radicals, as compared with closed-shell molecules. Therefore, the radicals are listed as important candidates of functional materials for electronic devices. In this review, we describe the latest science and application of organic radicals for secondary battery, semiconductor, and photochromism. We also review our recent results and the concept of organic light-emitting diode utilizing organic radicals as an emitter, which is called “organic radical light-emitting diode (ORLED)”.
