Surface-assisted cyclotrimerization of arylalkynes was studied on Au(111) by means of scanning tunneling microscopy (STM) under ultra-high vacuum (UHV) conditions. Upon thermal activation, cyclotrimerization of 1,3,5-tris-(4-ethynylphenyl)benzene proceeds readily and with high selectivity, and results in two-dimensional covalently bonded polyphenylene nanostructures exhibiting a honeycomb topology.
在超高真空(UHV)条件下,利用扫描隧道显微镜(STM)对芳基炔烃在Au(111)上的表面辅助环三聚反应进行了研究。在热活化作用下,1,3,5-三(4-乙炔基苯基)苯的环三聚反应容易且具有高选择性地进行,并生成呈现蜂窝拓扑结构的二维共价键合聚苯撑纳米结构。
