In this study, we have synthesised two novel p-type organic semiconductors in which chalcogen atoms are introduced along the long axis of molecules: 2-(pyran-4-ylidene)-1,3-benzodithiole (P-BT) and 2-(thiopyran-4-ylidene)-1,3-benzodithiole (TP-BT). P-BT forms...

Three 2-(thiopyran-4-ylidene)-1,3-benzodithiole (TP-BT) derivatives containing phenyl (1), 2-pyridyl (2) or 4-pyridyl (3) group on the benzene moiety were synthesized to investigate the relationship between molecular structure and their semiconductor properties....

Synthesis of a chiral molecular metal which shows metallic behaviour down to at least 4.2 K.

Trifluoromethylphenyl substituted phthalimides containing oligoselenophene or phenylselenophene substituents were synthesized, and their n-type semiconductor properties and photoresponsiveness were investigated.
