Small angle light and X‐ray scattering and scaling concepts are used to explore the intra‐ and inter‐molecular structure of two different classes of new materials: dendritic polymer and porphyrins systems. Whereas porphyrins in water are characterized, depending on their concentration and ionic strength, by the built‐up of extended clusters, dendrimers or ''starburst polymers'' display an internal self‐similar structure.
