Water-soluble chromophores shining like a star

In this NJC article, Cyrille Monnereau and his colleagues (University of Lyon, France) report an Atom Transfer Radical Polymerisation (ATRP) approach towards star-shaped chromophores, which bear hydrophilic oligomeric arms that form an “insulating shell” around the nano-sized molecules, resulting in their solubility in water with good conservation of their fluorescence quantum yield. These new amphiphilic chromophores are promising candidates for cellular fluorescence and photodynamic therapy. The authors claim that this synthetic strategy for photoactive species is straightforward and adaptable.
