The synthesis of a porphyrin rotaxane by dipolar cycloaddition takes advantage of the ditopic character of a phenanthroline-strapped porphyrin. The success of the click reaction was conditioned by the presence of both a coordinatively unsaturated metal in the porphyrin and a copper(I) bound to the phenanthroline, pointing at a new "tandem active metal template" mechanism.
通过偶极环加成反应合成卟啉轮烷利用了菲咯啉连接的卟啉的双位点特性。点击反应的成功取决于卟啉中配位不饱和金属的存在以及与菲咯啉结合的铜（I），这指向一种新的“串联活性金属模板”机制。
