Abstract

An A–D–D–A-type near-infrared non-fullerene small-molecule acceptor <bold>IDT2-DFIC</bold> with indacenodithiophene–indacenodithiophene (IDT2) as donating core and 2-(5,6-difluoro-3-oxo-2,3-dihydro-1<italic>H</italic>-inden-1-ylidene)malononitrile (2FIC) as electron withdrawing end groups has been synthesized.
