In recent years, supramolecular complexes comprising a poly(4-vinylpyridine) backbone and azobenzene-based halogen bond donors have emerged as a promising class of materials for the inscription of light-induced surface-relief gratings (SRGs). The studies up to date have focused on building supramolecular hierarchies, i.e., optimizing the polymer-azobenzene noncovalent interaction for efficient ...

As halogen bonds gain prevalence in supramolecular synthesis and materials chemistry, it has become necessary to examine more closely how such interactions compete with or complement hydrogen bonds whenever both are present within the same system. As hydrogen and halogen bonds have several fundamental features in common, it is often difficult to predict which will be the primary interaction in ...

Cyclic dimers and trimers of tetra-substituted benzenes, ((HOOC)2-C6H2-(NHI)2), are selected as convenient model systems for investigating NI…O=C halogen bond strength cooperativity. The four substituents in benzene chosen so that two them act acceptors (COOH) donors (NHI), shown the graphical abstract below. potential metal ion binding by each halogen-bonded aggregates is also investigated usi...

Tetrathiafulvalene on Pt: The enhanced stability of redox active self-assembled monolayers Pt electrodes allows for sensitive electrochemical anion detection assisted by non-covalent halogen bond formation.

The [N–I–N] + -type halogen bond performed as a powerful tool for the construction of functional axial chiral compounds, enriching toolbox asymmetric synthesis and optics.

Quantitative studies of the 1 : 1 complexes formed between perfluorohexyl iodide and a variety of hydrogen-bond acceptors have been used to probe the relationship between halogen bonding, hydrogen bonding, desolvation and the electrostatics of non-covalent interactions.

The electrochemical intramolecular cyclization of propargyl derivatives containing a carbon–halogen bond in N,N’-dimethylformamide at constant current in a diaphragmless cell has been developed using Ni(II) complexes as electron-transfer mediators.

Bifurcated Ipi and IO[double bond, length as m-dash]C halogen bonding interactions assist in formation of unique iodo-arene trimers leading to nanoscale channels in inclusion complexes of trimesic acid iodophenolate.
