Here, we report the synthesis and characterization of a series of contorted, yet noncentrosymmetrical, polycyclic aromatic hydrocarbons with a pentabenzo-fused coronene as the core framework. The parent pentabenzo[a,d,g,j,m]coronene (PBC) compound is shown to exhibit a shifted and rotated type of π-π stacking interactions, which render this series a semiconducting material. Single-crystal-based field-effect transistor devices of PBC exhibited efficient charge transport behavior, giving a p-channel field-effect mobility of 0.42 cm V s and an on/off ratio of 10.
在这里，我们报告了一系列扭曲但非中心对称的多环芳烃的合成和表征，它们以五并苯稠合的冠状物为核心框架。母体五并苯[a,d,g,j,m]冠状物（PBC）化合物显示出移位和旋转的π-π堆积相互作用，这使得该系列成为半导体材料。基于单晶的 PBC 场效应晶体管器件表现出有效的电荷输运行为，给出了 0.42cmV s 的 p 通道场效应迁移率和 10 的导通/关断比。
