Key Points

  • The aim is to explore the synthesis and properties of a nitrogen-doped hexa-peri-hexabenzocoronene derivative with unique geometry.
  • Developed a π-extended HBC derivative (5a) with a nitrogen-doped 5–7–7 ring fused to the core.
  • Evaluated photoluminescence and solubility properties in various solvents.
  • Assessed complex formation with fullerene C60 in solution.
  • 5a demonstrates enhanced photoluminescence properties.
  • Exhibited good solubility in n-hexane.
  • Formed a 1:1 complex with C60 in solution.

Abstract

Despite recent progress in single-ring defect engineering, the fusion of a 5–7–7 ring system to a single HBC core remains unexplored. Herein, we report a π-extended HBC derivative 5a that incorporates a nitrogen-doped 5–7–7 ring fused to the HBC core. 5a adopts a saddle-planar hybrid geometry, exhibits good solubility even in n-hexane, shows enhanced photoluminescence, and forms a 1:1 complex with C60 in solution.
