2,2′:6′,2″:6″,6-Trioxytriphenylamine: Synthesis and properties of the radical cation and neutral species
A flat radical: Oxygen-bridged triphenylamine 1 and its radical cation 2 were prepared. The neutral compound has a shallow bowl structure, whereas the radical cation is planar. The properties of the highly stable radical cation were clarified; such compou
