Overview

This work reveals a new synthetic method for helical twistacenes with enhanced properties for organic electronics.

Key Points

  • The aim is to develop a new synthetic methodology for precise control over C–C bonds in hexabenzocoronene-containing helical twistacenes.
  • Utilized an efficient synthetic methodology during the Scholl reaction
  • Synthesized the helical twistacene NG2 with high yield and low purification needs
  • Conducted X-ray analysis to measure the twist angle between NG1 and NG2
  • Achieved a twist angle reduction from approximately 145° in NG1 to 132° in NG2
  • Produced nanographenes with improved solubility and stability compared to planar analogues
  • Demonstrated interesting redox properties and optimal energy levels, enhancing potential as organic semiconductors
