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.

Abstract
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.File in questo prodotto:
