2,2′:6′,2′′:6′′,6‐Trioxytriphenylamine: Synthesis and Properties of the Radical Cation and Neutral Species

Abstract

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 compounds have potential applicability in electronic and magnetic materials.
