| abstract |
The present invention relates to the realization of particular supramolecular assemblies of dyes, in particular cyanines, called J aggregates. The invention concerns an assembly made up ofn a support including a mesoporous layer whereof the pores have an average BET diameter greater than 1.5 nm, macromolecules with dendritic architecture functionalizing said layer, at least in its pores, a layer of molecules from the family of cyanines interacting with the macromolecules with dendritic architecture and organized into J aggregates. |
