“…This observation stands in contrast to the so far favored 'in-line' mechanism of the enzyme with the reaction partners being 180 ° apart as is possible in the 6A,6C and 6A,6D regioisomers of 62 [95]. The general affinity of guanidinium cations for oxoanions and the spatial direction of the two NH-protons makes the bicycloguanidinium core presented in the preceding chapters also a useful building block for the design of nucleotide receptors [96]. Besides carboxytates (see Sect.…”

Switchable Assembly of Stable, Ordered Molecular Layers

Bipolar amphiphiles belonging to a,w-bis(4-amidinophenoxy)alkanes self-assemble in neutral or alkaline aqueous solution on acid-functionalised surfaces to form pH-switchable layers, with the amphiphiles oriented nearly perpendicular to the substrate. Layer thicknesses estimated by in situ ellipsometry, surface plasmon spectroscopy (SPS) or neutron reflection measurements correlated, within a certain amphiphile size range, with the molecular length of the amphiphile. Above a certain chain length, the characterisation by infrared reflection absorption spectroscopy (IRAS) indicated a crystallinelike order of the layered amphiphiles and a tendancy for bilayer formation was observed. These layers were stable and charge selective towards plasma proteins and charged surfactants.The layer stability was strongly pH dependant and no self-assembly was observed in acidic solutions. By cycling the pH between 9 and 2 rapid disassembly and reassembly of the layers was thus observed. The pH-switchable assembly can be used to restore a chemically selective interface after binding of a target molecule, for enhancement of sensor responses and potentially for optoelectronic or molecular electronic applications.

“…Conceivably, stacking of the bound adenine molecules accelerates the binding, and this can be seen as an artificial mimic of the base stacking in the double-helix formation of DNA. Recognition at the air-water interface provides median excellent medium for multi-point binding as seen in the recognition of ATP (figure 76C) [660,661]. Mixed host components spontaneously assembled into the optimized structure for aqueous guest recognition.…”

The controlled fabrication of nanometer-scale objects is without doubt one of the central issues in current science and technology. However, existing fabrication techniques suffer from several disadvantages including size-restrictions and a general paucity of applicable materials. Because of this, the development of alternative approaches based on supramolecular self-assembly processes is anticipated as a breakthrough methodology. This review article aims to comprehensively summarize the salient aspects of self-assembly through the introduction of the recent challenges and breakthroughs in three categories: (i) types of self-assembly in bulk media; (ii) types of components for self-assembly in bulk media; and (iii) self-assembly at interfaces.
