Composition containing, in a cosmetically or dermatologically acceptable medium, a compound that may be obtained by reaction between:
an oil bearing at least one nucleophilic and/or electrophilic reactive function, and
a junction group capable of establishing hydrogen bonds with one or more partner junction groups, the junction group bearing at least one reactive function capable of reacting with the reactive function borne by the oil, and also comprising at least one unit of formula (I) or (II):

noncovalent interactions involved. However, the outcome of biological processes is generally very well-defined often due to the competition of these interactions. In contrast, specificity in synthetic supramolecular systems is usually based on the presence of a minimum set of alternative assembly pathways. While the latter might simplify the system, it prevents the selection of specific structures and thereby

the hydrogen-bonding unit with respect to the metal coordinating site results in a T-symmetric cage, whereas by introducing flexibility either through a methylene linker or rotating benzene ring allows the formation of S4-symmetric cages with self-filled interior. In addition, the possibility to select between tetrahedral cages or helicates, and to control the dimensions of the aggregate, has been demonstrated

of spacerlength on the homoassociation and heteroassociation of end‐functionalized hydrogen‐bonding polymers based on poly(n‐butyl acrylate). Two monofunctional ureido‐pyrimidinone (UPy) end‐functionalized polymers were prepared by atom transfer radical polymerization using self‐complementary UPy‐functional initiators that differ in the spacerlength between the multiple‐hydrogen‐bonding group and
