A series of five D-A conjugated oligo(DPP- co -fluorene)s progressively consisting of 3, 5, 7, 9 and 11 monomers with molecular weights ranging between 1885 and 6428 and chain lengths ranging between 3 and 10 nm have all been synthesized in a single step by direct C-H arylated coupling, among which the 10.1 nm scale O 5 is the longest DPP-based conjugated oligomer reported ever.
