Tuning the Twist by Molecular Design: A New Strategy for Hexabenzocoronene‐Containing Helical Twistacene

Chemistry – A European Journal, EarlyView.
An efficient Scholl–based strategy enables precise control of the C–C bond to access the first hexabenzocoronene–containing helical twistacene (NG2). The resulting nanographene shows pronounced helical distortion, high stability, enhanced solubility, and promising redox and optoelectronic properties.
