Redox-Active Hydrocarbons: Isolation and Structural Determination of Cationic States toward Advanced Response Systems.

Invited for this month's cover is the group of Prof. Yusuke Ishigaki at Hokkaido University, Japan. The cover picture shows a cyclic voltammogram drawn in the style of an ink painting, along with the structures of cationic species composed of pure hydrocarbons. The sunrise, a metaphor for X-rays irradiated on cations, is reminiscent of the dawn of redox chemistry of hydrocarbons. Elucidation of their redox properties should provide important insights into the development of organic electronic devices. The cover was designed by YAP Co., Ltd. More information can be found in the Review by T. Harimoto and Y. Ishigaki.
