Abstract
Crystalline materials that comprise π-electron organic molecules exhibit various interesting physical properties and functionalities, related to electrical conductivity, magnetism, optical properties, etc. Conventionally, such properties and functionalities are determined or controlled by the intermolecular π-electron interactions in the crystal. Recently, however, the switching or control of the electronic structure and physical properties based on hydrogen dynamics was realized in a series of purely organic conductors. In this account article, the structure, properties, and switching phenomenon of this new type of organic conductors developed by utilizing proton- and π-electron-donating/accepting abilities are summarized. In addition, a highly polarized π-electron donor-acceptor type semiconductor molecule obtained in connection with the above conductors is also described.Keywords
