Abstract
  • Abstract The synthesis of two new thieno(bis)imide (TBI, N) end functionalized oligothiophene semiconductors is reported. In particular, trimer (NT3N) and pentamer (NT5N) have been synthesized and characterized. Two different synthetic approaches for their preparation were tested and compared namely conventional Stille cross coupling and direct arylation reaction via C-H activation. Theoretical calculations, optical and electrochemical characterization allowed us to assess the role of the ?-conjugation extent, i.e., of the oligomer size on the optoelectronic properties of these materials. In both {TBI} ended compounds, due to the strong localization of the {LUMO} orbital on the {TBI} unit, the {LUMO} energy is almost insensitive to the oligomer size, this being crucial for the fine-tailoring of the energy and the distribution of the frontier orbitals. Surprisingly, despite its short size and contrarily to comparable TBI-free analogues, {NT3N} shows electron charge transport with mobility up to ?N = 10-4 cm2 V-1 s-1, while increasing the oligomer size to {NT5N} promotes ambipolar behavior and electroluminescence properties with mobility up to ?N = 0.14 cm2 V-1 s-1 and to ?P = 10-5 cm2 V-1 s-1.
