摘　　要：Graphyne,a remarkable two-dimensional carbon allotrope,has attracted significant attention in the field of materials science due to its unique properties and potential applications.Because of the special arrangement of their sp-and sp^(2)-hybridized carbon atoms,these structures display a wide range of geometrical and electronic characteristics as well as homogeneous pores of varying sizes,making them suitable for a variety of practical applications.In recent years,the synthesis of the thin film products of graphyne and its derivatives has typically been documented.To date,however,it remains challenging to synthesize atomically precise single-layered graphyne and its derivatives.Herein,we report a facile strategy to synthesize single-layered hydrogen-substituted γ-graphdiyne on the Au(111)surface through dehalogenation and intermolecular coupling polymerization.Its geometric atomic structure was investigated by scanning probe microscopy.Combined with theoretical results,we reveal its semiconducting property.
