Key Points

To establish a synthetic route to novel nitrogen-doped nanographenes, specifically fully and partially fused hexaazasuperbenzenes, and evaluate their optical characteristics.
Employed [2 + 2 + 2] cyclotrimerisation to construct hexasubstituted molecular precursors.
Subjected precursors to varied oxidative cyclodehydrogenation reaction conditions to promote ring fusion.
Evaluated and compared the spectroscopic properties of the resulting fully fused and 5/6th partially fused structures.
Successfully synthesized novel fully fused and 5/6th partially fused hexaazasuperbenzene frameworks.
Identified distinct spectroscopic profiles between the fully fused and partially fused molecular derivatives.
