synthesis of racemic [6]hexahelicene‐7‐carboxylic acid by cross‐coupling of a bicyclic and a tricyclic component is described. A metal‐catalyzed ring‐closure is also a fundamental component of the synthetic approach. Scanning tunneling microscopy (STM) measurements of the racemate self‐assembled on Au(111) at liquid–solid interface revealed the formation of ordered racemic 2D crystals.
描述了通过双环和三环组分的交叉偶合来聚合外消旋[6]六螺旋烯-7-羧酸的方法。金属催化的闭环也是合成方法的基本组成部分。在液-固界面上自组装在Au(111)上的外消旋体的扫描隧道显微镜(STM)测量揭示了有序外消旋2D晶体的形成。
