An organic redox active compound with reversible storage of charge is disclosed. The material characterized by a formula R-M-Y-T. According to some aspects, R represents a deconjugating group, M represents an organic redox active fragment, not comprising any metal ion or metal, capable of reversibly storing at least one charge, T represents a tripod group comprising three groups F, capable of being chemically grafted to a surface of a solid substrate, and Y represents a spacer group separating M from T. A substrate on which the compounds are grafted, a molecular memory device including the compound or the substrate, and an electronic apparatus including the molecular memory device are also disclosed.
