In this thesis different aspects of functional hydrogen-bonded (double and tetrarosette) assemblies are described. The functions were inspired by naturally occurring mechanisms such as molecular recognition, supramolecular chirality and its origin, and biostrategies for the correct folding of proteins. The studies presented in this thesis are focused on the different `social¿ roles of these (chiral) assemblies: As hosts able to accommodate simultaneously different (chiral) guest molecules, as molecular sergeants whose (chiral) orders are followed by molecular soldiers, and as molecular chaperones inhibiting incorrect interactions in the formation of the assemblies
