The preparation of novel families of phosphorus‐based macromolecular architectures called “onion peel” phosphorus nanodendritic systems is reported. This construct is based on the versatility of methods of synthesis using several building blocks and on the capability of these systems to undergo regioselective reactions within the cascade structure. Sustainable metal‐free routes such as the Staudinger reaction or Schiff‐base condensation, involving only water and nitrogen as byproducts, allow access to several dendritic macromolecules bearing up to seven different phosphorus units in their backbone, each of them featuring specific reactivity. The presence of the highly aurophilic PNPS fragment enables selective ligation of Au I within the dendritic framework.
