Supramolecular construction

FIG. 14 Schematic illustration of an archaeal cell envelope structure (a) composed of the cytoplasmic membrane with associated and integral membrane proteins and an S-layer lattice, integrated into the cytoplasmic membrane, (b) Using this supramolecular construction principle, biomimetic membranes can be generated. The cytoplasmic membrane is replaced by a phospholipid or tetraether hpid monolayer, and bacterial S-layer proteins are crystallized to form a coherent lattice on the lipid film. Subsequently, integral model membrane proteins can be reconstituted in the composite S-layer-supported lipid membrane. (Modified from Ref. 124.)... 

Switching the roles of the zinc porphyrin template and N-donor adapter provides an alternative mode for the supramolecular construction of biden-tate ligands (Scheme 32). Complex 26 derived from mixing three equivalents of template 24 with two equivalents of monodentate phosphite ligands 23 furnished a rhodium catalyst which displayed good regioselectivity toward... 

Very recently, MacGillivray et al. succeeded in the supramolecular construction of molecular ladders in the solid state using a linear template approach [48]. They designed the cocrystals 1,3-benzenediol (resorcinol) or a derivative with an all-trans-bis(4-pyridyl)butadiene or hexatriene, in which two resorcinol molecules preorganize two polyene molecules through two hydrogen bond interactions, for [2-1-2] photoaddition (Scheme 5). In this design, two polyenes would...

Metallodendrimers can be of supramolecular construction [116] (see Section 2.6), formed by metal/ligand complexation (coordination chemistry), or also produced by covalent bonding. 

The following papers focus mainly on various aspects associated with the self-assembly of peptides. Peptides are relatively short sequences of amino acids, typically less than 50. The limited number of residues brings simplicity but still allows for sufficient differentiation to study self-assembly in its various details. The compositional freedom of the primary molecule allows for a sufficiently rich hierarchical structure creation through aggregation of individual peptides into supramolecular constructs resulting in interesting materials. This chapter looks into relevant patent literature as a reflection of the state of the art of technology in peptide self-assembly. 

Hydrogen bonding is the most important directional Interaction responsible for supramolecular construction [17], Appendix 1 illustrates several typical hydrogen bond patterns which are present in two-component molecular crystals. Appendix 2 exemplifies a variety of reported cocrystals selected mainly fiom the recent papers [18], Not only strong hydrogen bonds (i.e, 0—H "0, 0—H- N,... 

Hydrogen bonding, the master key for molecular recognition, is the most reliable directional interaction in supramolecular construction and its significance in crystal engineering and molecular recognition can be scarcely...
