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 31 P NMR spectroscopy, with the appearance of several signals for the phosphorus atoms included in the macrocycle. (© Wiley‐VCH Verlag GmbH & Co.
