Bithiophene imide
WebImide-functionalized arenes have been one of the most promising acceptor (A) units in organic solar cells (OSCs). However, dithienophthalimide (DPI), a hybrid of thieno-[3,4-c]pyrrole-4,6-dione (TPD) and bithiophene imide (BTI) units, has not been revisited since its first synthesis, likely owing to the high synthetic cost of the reported method.In this … WebWe synthesized four n-type conjugated polymers comprising a bithiophene imide (BTI) unit and 3,3′,4,4′-tetrafluoro-2,2′-bithiophene (4FBT) or (E)-1,2-bis(3,4-difluorothien-2-yl)ethene (4FTVT) via direct arylation polycondensation, and comprehensively studied the optical, electrochemical and charge transport properties of the polymers.. Increasing the BTI …
