In-Depth Information
In the last case, the investigated luminophore is not covalently linked to the
dendritic structure, but it is encapsulated in its cavities. Therefore, the study of
fluorescence anisotropy of encapsulated chromophores may evidence the possibility
of restricted rotation of the chromophore inside the dendrimer cavities, the energy
migration processes when more than one luminophore is encapsulated in the same
dendrimer, and, in some specific cases, the association process.
Fluorescence anisotropy reveals to be once more a very useful tool to investigate
dendrimer structures and energy migration processes.
