除双噻吩基和五噻吩基自由基外，噻吩的四种低聚物的阳离子和阴离子均已生成，并通过ESR光谱进行了表征。环间键的顺反异构性与先前报道的2,2 ' -二硫乙烯基阴离子的异构性相似，已观察到三硫乙烯基阳离子和阴离子自由基的异构性，而四硫乙烯基和五硫乙烯基的异构性没有直接证据。
The radical cations and anions of the four lower oligomers of thiophene have been generated and characterized by means of ESR spectroscopy, with the exception of bi- and quinque-thienyl radical cations. cis–trans isomerism about the interannular bonds, similar to that previously reported for 2,2′-dithienyl radical anion, has been observed for terthienyl cation and anion radicals, while no direct evidence of such isomerism could be obtained for quaterthienyl and quinquethienyl.
