Metallated phthalocyanines as the core of dendrimers - Synthesis and spectroscopic studies

The complexation of a first-generation dendrimer possessing a metal-free octasubstituted phthalocyanine as its core has been carried out with copper and cobalt chlorides. In the case of the cobalt complex, the synthesis of the dendrimer has been pursued up to the eighth generation. The progressive influence of the branches upon the core has been studied with dendrimers from generation 1 to generation 7, using UV/Vis spectroscopy. These data indicate a progressive isolation of the core.
