The synthesis of a block codendrimer (g3-PBE-b-g3-PMDC), composed of a third-generationpoly(benzyl ether) (PBE) monodendron and an aliphatic polyether (PMDC) monodendron is reported. InTHF/diiospropyl ether (1:1) the PMDC block functions as a "hydrophilic" block, while the PBE acts as a"hydrophobic" block. The codendrimer can form interdigitated layers leading to vesicle formation. Tappingmode atomic force microscopy (AFM), dynamic light scattering (DLS), and transmission electron microscopy(TEM) were used to characterize the vesicles. The effect of molecular architecture on the formation of theinterdigitated layers and vesicles was studied.
