  Systematic Evaluation of 2,6-Linked Pyridine–Thiophene Oligomers

  摘要：

  An efficient synthesis of alternating 2,6-linked pyridine-thiophene (Py-Th) oligomers allows systematic evaluation of their optical and electrochemical properties. The six- and eight-ring oligomers are revealed to be brightly luminescent, even in the solid state. The oligomers are easily reduced but cannot be electrochemically oxidized. The longer oligomers have reduction potentials similar to those reported for pyridine-thiophene polymers of less defined structure. Protonation of the pyridine or substitution at C4 are shown to further modulate the electronic properties and, in combination with the low-lying absolute LUMO energies, these data suggest that the compounds are potential n-type materials worthy of further study.
