摘要
A phosphorus-containing dendron was synthesized and grafted to a tetraphosphorus macrocycle. The presence of such bulky substituents allowed for the first time the amplification of topological differences in the macrocycle. These differences become detectable by P-31 NMR spectroscopy, with the appearance of several signals for the phosphorus atoms included in the macrocycle.
