报告摘要:Reduction in the dimensionality of graphene in the form of graphene quantum dots and graphene nanoribbons has compensated for the lack of a bandgap in the extended 2D material. These graphene nanostructures (nanographenes) exhibit finite bandgaps because of quantum confinement, making them attractive as next-generation semiconductors.[1] The size and edge topology of nanographenes are essential to their electronic properties, which requires a bottom-up method to synthesize well-defined structures. In this talk, I will present the chemical syntheses of nanographenes with atomic precision, with an emphasis on heteroatom-doped nanographenes.[2] A new type of “graphitic” N-doped nanographene molecules with profound antiaromaticity,[3] and BNS-doped nanographene molecules exhibiting non-planar geometries[4] will be introduced. Furthermore, stable periacene-based nanographenes with OBO-functionalized zigzag edges will be discussed, including the peritetracene analogue[5] synthesized by solution chemistry and the longest perihexacene analogue[6] generated via surface-assisted cyclodehydrogenation. These results have further afforded the first chiral (4,1)-graphene nanoribbons with lateral alignment, providing opportunities for future optoelectronic applications.[7]
