Diversity-oriented synthesis of tetrathia[8]circulenes by sequential C–H borylation and annulation†
Abstract
We have succeeded in the diversity-oriented synthesis of tetrathia[8]circulenes by sequential C–H borylation and annulation from cyclic tetrathiophene, and time-resolved microwave conductivity studies have proved that the intrinsic hole mobilities of tetrathia[8]circulenes are dependent on the chain length of the alkyl substituents at the peripheral positions.
