Outline of Final Research Achievements

We have developed novel n-type organic semiconductors for organic transistors and solar cells by considering molecular-orbital energy levels and intermolecular interactions. For example, heterocyclic compounds with electron-accepting groups and long-alkyl substituents afforded air-stable n-type organic transistors by a solution method. Heterocyclic compounds with non-symmetric or non-planar structures worked as n-type semiconductors for organic solar cells.
