An approach for the synthesis of pyrene-fused acenes that allows the introduction of electron-withdrawing cyano groups in key positions that simultaneously (i) induce twists in the aromatic framework and (ii) stabilize the LUMO level is reported. This combination of steric and electronic features provide a twisted, stable, and n-type tetrabenzoheptacene as confirmed by a combination of theoretical calculations and optical, electrochemical, thermal, and electrical characterization.
本文报道了一种合成并苯稠环芳烃的方法，该方法允许在关键位置引入吸电子氰基，同时（i）诱导芳构环的扭曲，（ii）稳定 LUMO 能级。这种空间位阻和电子特性的组合提供了一个扭曲的、稳定的和 n 型的四苯并十七稠环，这一点通过理论计算和光学、电化学、热学和电学特性的综合分析得到了证实。
