• bathochromic shift together with an emission-band broadening in contrast to their emission spectra recorded in solution. The supramolecular arrangement in the solid state of indenopyrone 6a is ensured by a number of non-covalent interactions such as intermolecular H-bonding, C–H···π and π···π contacts

• higher concentration of C18-PeBGF. We found a fibrillar supramolecular arrangement being up to several hundred nanometers long at 2 mM peptide concentrations (Figure 2). These fibers appeared predominantly as single, rather elongated structures. However, we found sheet like structures, possibly from a

Indeed aggregation of viruses can only be explained by the formation of a supramolecular arrangement of amphiphilic peptides forming a surface with multiple ligands recognizing HA but not by a monomeric organisation of amphiphilic peptides. Amphiphilic peptides interfere with virus binding to cells The

This showed that the supramolecular arrangement of molecules in the crystal plays a more important role for reaction control than the simple alignment of double bonds. Long-range molecular movements within crystals upon photochemical reaction and even

• starting materials of a photochemical reaction are used and the supramolecular arrangement [10] may control the regio- and stereoselectivity of the photo-process. The enantioselective photochemical conversion of chiral crystals into optically active products has also been described [11]. Some approaches

By themselves ionic liquids are organic salts (i.e. totally composed of cations and anions) that are

With the support of dilatometry, models for the lamellar supramolecular arrangement of the salts are proposed and its evolution is discussed as a function of the
