Donor-acceptor oligomers, composed of 2-Amino-7-bromofluorene (fluorene) as the electron donor and perylene-3,4,9,10-tetra carboxylic dianhydride (perylene) as the electron acceptor, were prepared and used to fabricate a one-dimensional fibrillated optoelectronic device. Typically, Perylene bisimides (PBI) belong to a class of n-type chromophores exhibiting relatively high electron mobility, large molar absorption coefficients, fluorescence quantum yield, as well as good thermal and photochemical stabilities. Two fluorene and benzothiazole are synthesized by Suzuki coupling, and A long chain is formed by attaching 6 alkyl chains on one side of flourene. The long chain thus synthesized is a chromophore, which is attached to both side of perylene to synthesize N,N'-((7,7'-((1,3,8,10-tetraoxo-3,3a,7a,8-tetrahydroanthra[2,1,9-def:6,5,10-d'e'f']diisoquinoline-2,9(1H,5aH,5bH,10H)-diyl)bis(9H-fluorene-7,2-diyl))bis(benzo[c][1,2,5]thiadiazole-7,4-diyl))bis(9H-fluorene-7,2-diyl))bis(3,4,5-tris(2,5,8,11,14,17-hexaoxanonadecan-19-yloxy)benzamide) (P4F6A). Thus, the products allow for conjugation over a wider wavelength range. It is possible to conform π- π stackings of perylene and fluorene, that have more photochemical stability. Synthesized oligomers can be confirmed by NMR spectroscopy and MALDI-TOF.
