Fig. 7: Energy landscapes of self-assemblies from Janus dendrimers with –OH end groups in the absence of ethanol.

a Cryo-TEM images of self-assemblies vitrified at the indicated temperatures during the heating/cooling cycle. Arrows indicate non-interdigitated regions where membrane fission leads to the formation of ULVs. Scale bars are 200 nm. b Schematic illustration of locked interdigitation via hydrogen bonding between bilayers in selected regions highlighted by white dashed boxes in (a).
