Abstract: Abstract Two new small-molecule nonfullerene acceptors containing methyl- and fluorine-substituted 2-(2,3-dihydro-3-oxo-1H-inden-1-ylidene)propanedinitrile (INCN) as end groups, namely, NFBDT-Me and NFBDT-F, were designed, synthesized and applied in organic solar cells. The influence of the methyl and fluorine… read more here.
