Research Abstract

Peripherally π-electron conjugated compounds incorporated by chalcogen atoms have been investigated as new entity of organic semiconductors. Sulfur incorporated molecule assumes unique HOMO distribution as well as herringbone packing structure with excellent molecular overlap. Indeed, single crystal transistor using this material exhibits high performance with the mobility reaching 1.6 cm^2/Vs.
