The specific functionalization of cyclotriphosphazene for the synthesis of smart dendrimers

Abstract

Hexachlorocyclotriphosphazene is an old compound which affords very new properties in the field of dendrimers. Indeed, it can be used as a branching point for the rapid synthesis of highly dense dendrimers, but also for the synthesis of dendrimers having precisely one function different from all the others. These types of dendrimers are useful in the field of materials, affording highly reusable catalysts, chemical sensors, or supports for cell cultures. However, the most developed uses concern fluorescence. These dendrimers have been used for in vivo imaging, and for trying to elucidate biological mechanisms, in particular for anti-inflammatory dendrimers. This review will display important examples in the field.
