Enantiomeric resolution of supramolecular helicates with different surface topographies.

The enantiomeric resolution of an extended range of di-metallo supramolecular triple-helical molecules are reported. The ligands for all complexes are symmetric with two units containing an aryl group linked via an imine bond to a pyridine. Alkyl substituents have been attached in different positions on the ligand backbone.

Selective intercalation of six ligand molecules in a self-assembled triple helix.

The addition of a ligand molecule to an artificial self-assembled triple helix leads to the selective intercalation of two hydrogen-bonded trimers in specific binding pockets. Furthermore, the triple helix suffers large conformational rearrangements in order to accommodate the ligand molecules in a highly organized manner.

Dynamic combinatorial libraries based on hydrogen-bonded molecular boxes.

This article describes two different types of dynamic combinatorial libraries of host and guest molecules. The first part of this article describes the encapsulation of alizarin trimer 2a3 by dynamic mixtures of up to twenty different self-assembled molecular receptors together with the amplification and selection of the best binder. Receptors (1a-d)3.

Selective self-organization of guest molecules in self-assembled molecular boxes.

This article describes the synthesis and binding properties of highly selective noncovalent molecular receptors 1(3).(DEB)6 and 3(3).(DEB)6 for different hydroxyl functionalized anthraquinones 2.

Complexation of phenolic guests by endo- and exo-hydrogen-bonded receptors.

This article describes the complexation of phenol derivatives by hydrogen-bonded receptors. These phenol receptors are formed by self-assembly of calix[4]arene dimelamine or tetramelamine derivatives with 5,5-diethylbarbiturate (DEB) or cyanurate derivatives (CYA). The double rosette assemblies 3(3).

Self-assembly of polar functionalities using noncovalent platforms.

Small peptide fragments functionalized with dimelamine units spontaneously form well-defined assemblies. The hydrogen-bond donating and accepting sites in the peptide units are perfectly compatible with the hydrogen-bond assembly motif and slightly stabilize the assembly via additional hydrogen-bond formation.
