Abstract
Dendrimers with bulky repeating units containing up to 43 benzene ring s (in 9) have been obtained by using a repetitive divergent synthetic strategy (three generations). The new functional dendrimer 13 containi ng six azobenzene units at the periphery was synthesized allowing a re versible switching of the shape and size of the molecule upon irradiat ion. An X-ray structure analysis of the dendritic molecule 3a shows th e inclusion of acetonitrile.
