✦ Synopsis


The exceptional structure of the first reconstructed micelles is formed by the self‐assembly of amphiphilic dendrocalixarenes in aqueous solution. A. Hirsch, C. Böttcher, and co‐workers report in their Communication on page 2959 ff. that the relatively rigid T‐shaped structure of the molecule allows efficient backfolding and thus the formation of aggregates with high curvature. Structural determination of the nanocontainers permits characterization of the micellar architecture at the molecular level.
