Introduction of nonhexagons and/or heteroatoms allows for finely tuning the physicochemical properties of nanographenes. Heteroatoms doping have dominated the modulation of nanographenes with tunable bandgap, rich electrochemical activities and so on. The pair of nonhexagons, for instance, pentagon-heptagon pairs, have furnished nanographenes with aromatic and/or antiaromatic characteristics, open-shell properties and so on.

1 Introduction Since its debut in 2004, the exceptional electronic, thermal, and mechanical properties of graphene have been vividly and thoroughly demonstrated in materials science.1-5 However, the application of graphene in field-effect transistors (FETs) has been limited due to its lack of a band gap.6 Generally, reducing the dimensionality of graphene to zero- and/or one-dimensional nanoscale fragments (named nanographenes, NGs) with defined size and edge structures is an option for...

Graphical Abstract In this study, novel nanographenes bearing N-doped pentagon-heptagon pairs were synthesized through a facile ring expansion strategy. Modifications of heptagon spacers have endowed N-doped nanographenes with tunable physicochemical properties. This ring expansion method was further explored to synthesize diverse N-doped nanographenes containing pentagon-octagon pairs, demonstrating the high efficiency of the proposed method.
