A new core, 4H-diselenopheno[3,2-b:2′,3′-d]pyrrole (DSP), was reacted with tetracyanoethylene, and three products, mono-tricyanovinyl, bis-tricyanovinyl, and quinoidal, were isolated and compared with the respective 4H-dithieno[3,2-b:2′,3′-d]pyrrole (DTP) derivatives using cyclic voltammetry, UVa-vis absorption, and differential scanning calorimetry analyses. Organic field-effect transistors were fabricated using solution-processed films, and only one derivative, bis-tricyanovinyl-DSP, exhibited transistor behavior with μe reaching 8.7 × 10a-4 cm 2/V·s. This enhancement of the electron-transporting properties in comparison with DTP derivative is attributed to stronger LUMOa-LUMO interaction due to a larger size of selenium atom, which in the case of the bis-tricyanovinyl derivative, has wave function density on the chalcogen.

Fluorene and dithieno[3,2-b:2′,3′-d]pyrrole (DTP) containing conjugated polymers, {2,7-[9,9-didodecylfluorene]-alt-2,6-[N-dodecyldithieno(3, 2-b:2′,3′-d)pyrrole]} (PF-DTP1) and {2,7-[9,9-didodecylfluorene]- alt-2,6-[N-3,4,5(n-dodecyloxy)phenyldithieno(3,2-b:2′,3′-d)pyrrole]} (PF-DTP2), have been successfully synthesized using Suzuki polycondensation. These polymers possess excellent thermal stability with decomposition temperatures over 365 °C under Ar. The introduction of soluble side chains on the DTP units and incorporation with soluble dialkyl-substituted fluorene resulted in highly soluble polymers with novel optoelectronic properties. The supramolecular complex formation of these DTP containing polymers with single-walled carbon nanotubes (SWNTs) has been studied, and it was found that these polymers can form strong supramolecular polymer-nanotube assemblies and produce stable complexes in solution. UV-vis-NIR absorption, photoluminescence excitation (PLE), and Raman spectroscopy were used for the characterization and identification of the nanotube species that are present in THF solution. The strong nanotube emission was observed from individual SWNTs even after removal of excess free polymer by filtration and washing. On the basis of these two polymers, it was found that the interactions with the SWNT surface are more strongly dictated by the polymer backbone than the side chain, though further studies may be warranted.
