The synthesis of a threefold symmetric nanographene with 19 cata‐fused benzene rings distributed within six branches is reported. This flat dendritic starphene, which is the largest unsubstituted cata‐condensed PAH that has been obtained to date, was prepared in solution by means of a palladium‐catalyzed aryne cyclotrimerization reaction and it was characterized on surface by scanning probe microscopy
报道了三重对称纳米石墨烯的合成,该纳米石墨烯具有分布在六个分支中的19个催化融合的苯环。这种扁平的树枝状星形苯酚是迄今为止获得的最大的未取代的催化缩合多环芳烃,是通过钯催化的芳烃环三聚反应在溶液中制备的,并通过具有原子分辨率的扫描探针显微镜对表面进行了表征。
