In this study, we have successfully synthesized a portion of hydrogen-substituted graphdiyne(HsGDY) on Au(111) in the air using the drop method. HsGDY is a two-dimensional material consisting of an sp-sp² carbon framework that has attracted much attention in recent years because of its large pore structure and band gap compared to existing nanocarbon materials such as graphene [1]. Our novel method allows us to synthesize very useful new materials consisting of carbon skeletons in a very short time without the use of toxic pyridine[3] or expensive ultra-high vacuum environments[5] as in previous studies. Furthermore, this technique does not limit the size of the substrates to be synthesized, which represents a major advance toward practical applications. Our research provides a new way to obtain remarkable materials at low cost.
