我们合成了一类新型的噻吩稠合磷杂环戊二烯衍生物二噻吩并[3，4-B：3′，4 ′-d]磷杂环戊二烯。这些二噻吩磷杂环戊二烯被发现通过在外围芳基基团上引入供电子或吸电子基团而表现出分子内电荷转移相互作用。也就是说，它们表现出吸电子磷杂环戊烯和给电子噻吩的独特杂化特性。
We have synthesized dithieno[3,4-b:3′,4′-d]phosphole derivatives as a new type of thiophene-fused phospholes. These dithienophospholes were found to show intramolecular charge transfer interactions by introducing electron-donating or -withdrawing groups on the peripheral aryl groups. Namely, they exhibit the unique hybrid character of electron-withdrawing phosphole and electron-donating thiophene.
