摘要
A series of new zinc phthalocyanine dendrimers with an increasing branched shell of oligoethylene glycol end groups has been synthesized. Owing to the presence of these hydrophilic termini at the dendrimer surface, all compounds are highly soluble in a wide range of solvents including water. The monodispersity of the amphiphilic dendrimers has been unambiguously evidenced by both NMR and MS techniques. UV-vis experiments point out that the tendency of the central phthalocyanine chromophore to aggregate in polar protic solvents is not significantly reduced regardless of the dendritic shell surrounding the macrocyclic chromophore.
