An electron-deficient nanosized polycyclic aromatic hydrocarbon with enhanced anion–π interactions

Abstract

A super-π-acidic nanosized polycyclic aromatic hydrocarbon with six imide groups at the corners was prepared from the pre-synthesized 7,8-dichlorobenzo[ghi]perylenetriimide through a combination reaction of Ullmann-type and C–H transformation, which exhibited enhanced anion–π interactions with various anions.
