As reported by Si Kyung Yang and Steven C. Zimmerman on page 3023 , perylenediimides (PDIs) are encapsulated within polyglycerol dendrons, which confer high water‐solubility on the PDIs in aqueous media while retaining their excellent fluorescent properties. The PDI‐cored dendrimers retain their fluorescence signals in the presence of a variety of metal ions as fluorescence quenchers. Furthermore, intramolecular cross‐linking of the polyglycerol dendrons not only enhances the photostability but also reduces the size of dendrimers.
