ABSTRACTA series of substituted phenylene ethynylene diazonium salts were prepared from the corresponding anilines by the action of nitrosonium tetrafluoroborate in sulfolane-acetonitrile solvent. Formation of self-assembled layers of the diazonium salts in acetonitrile solution was demonstrated on Au, Cu and Pt surfaces. The self-assembly rate of the diazonium salts was found to be markedly dependent on the electron withdrawing character of the substituents attached to the aromatic rings.

Chiral oligo(methylene-p-phenyleneethynylene)s can form vesicular assemblies no matter whether side chains and solvents are hydrophilic or hydrophobic. The self-assembly processes are highly independent of molecular design and chemical environments.

Self Aggregation

The ability of trans- and cis-1,2-glucopyranosyl and cyclohexyl ditriazoles, synthesized by CuAAC "click" chemistry, to form gels was studied, their physical properties determined, and the self-aggregation behavior investigated by SEM, X-ray, and EDC studies. The results revealed that self-assembly was driven mainly by π–π stacking interactions, in addition to hydrogen bonding, with the aromatic rings adopting a high degree of parallelism, as seen in crystal packings and ECD data. Furthermore, π–bromine interactions between the bromine atom of the aryl substituents and the triazole units might also contribute to an overall stabilization of the supramolecular aggregation of bis(4-bromophenyl)triazoles. The trans or cis spatial disposition of the triazole rings is highly important for gelation, with the cis configuration having higher propensity.

Amino acids adsorbed on single-crystal metal surfaces have emerged as prototypical systems for exploring the properties that govern the development of long-range chirality in self-assembled monolayers and supramolecular 2D networks. In this study, we characterise the self-assembly mechanism for glycine on the Cu(110) surface.
