一种新型的copillar[4+1]芳烃结合烷基硫醇取代基的合成分三步进行，其结构特征在于作为柱[n]芳烃的第一个例子，将两个末端硫醇在同一芳环上。通过标准浸渍技术将大环连接到金电极上。循环伏安法证明了Li+相对于其他碱金属阳离子的选择性。共柱[4+1]芳烃还被用作制备3nm金纳米颗粒的封端剂。
A novel copillar[4+1]arene incorporating alkylthiol substituents was synthesised in three steps and structurally characterised as the first example of a pillar[n]arene to incorporate two terminal thiols on the same aromatic ring. The macrocycle was attached to gold electrodes through a standard dipping technique. Cyclic voltammetry demonstrated selectivity for Li+ over other alkali metal cations. The copillar[4+1]arene was also used as a capping agent in the preparation of 3nm gold nanoparticles.
