Three-Dimensional Intramolecular Exchange Interaction in a Curved and Nonalternant π-Conjugated System: Corannulene with Two Phenoxyl Radicals

摘要

In recent years, curved re-conjugated molecules such as fullerenes and carbon nanotubes have attracted much attention not only in chemistry but also in materials science. Their intra/intermolecular interactions within/between three-dimensional (3D) curved π-electron networks play intrinsically vital roles in their unique properties and functionalities. Among them, intramolecular magnetic interaction between electronic spins on a curved π surface was extensively studied for ionic species of C_(60) such as C_(60)~(2-) and C_(60)~(3-).
