Summary
This study introduces cyclic diaryliodonium ions as potent biaxial halogen bond donors for creating supramolecular materials. These interactions enable controlled chirality, leading to novel supramolecular glasses, deep eutectic solvents, and light-responsive materials.
Area of Science:
- Supramolecular Chemistry
- Organic Chemistry
- Materials Science
Background:
- Hypervalent iodine(III) compounds are established organic synthesis reagents.
- Their utility as biaxial halogen bond donors in supramolecular materials remains largely unexplored.
- Biaxial halogen bonding offers unique directional interactions for material design.
Purpose of the Study:
- To explore the potential of cyclic diaryliodonium ions as biaxial halogen bond donors.
- To investigate the formation and properties of supramolecular complexes with chiral acceptors.
- To develop novel supramolecular materials with tunable properties.
Main Methods:
- Synthesis of cyclic diaryliodonium ions.
- Complexation with phenanthroline or acridine acceptors bearing chiral pendants.
- Characterization of supramolecular assemblies in solution and solid states.
- Investigation of chiroptical properties and solid-state behaviors (amorphous, deep eutectic).
Main Results:
- Cyclic diaryliodonium ions exhibit strong binding affinity towards chiral acceptors via biaxial halogen bonding.
- Supramolecular chirality is controllably induced in solution.
- Stable supramolecular glasses and deep eutectic solvents were successfully prepared.
- Light-triggered luminescence was achieved through a hydrogen atom transfer mechanism.
Conclusions:
- Cyclic diaryliodonium ions are effective biaxial halogen bond donors for supramolecular chemistry.
- This approach allows for rational design and control of supramolecular chirality and material properties.
- The developed materials show potential applications in anti-counterfeiting and display technologies.

8.5K
Coordination compounds and complexes exhibit different colors, geometries, and magnetic behavior, depending on the metal atom/ion and ligands from which they are composed. In an attempt to explain the bonding and structure of coordination complexes, Linus Pauling proposed the valence bond theory, or VBT, using the concepts of hybridization and the overlapping of the atomic orbitals. According to VBT, the central metal atom or ion (Lewis acid) hybridizes to provide empty orbitals of suitable...

Isomerism in Complexes
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...

01:19Complexation Equilibria: The Chelate Effect
495
In complexation reactions, metal atoms or cations interact with ligands to form donor-acceptor adducts called metal complexes. Ligands that bind through one donor site are monodentate, ligands with two donor sites are bidentate, and those with more than two donor sites are polydentate ligands. For example, ethylene diamine is a bidentate ligand that binds through two nitrogen donor atoms, forming a five-membered ring. EDTA is a polydentate ligand that binds through four oxygen and two nitrogen...

Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

Crystal Field Theory
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.

01:13Electrophilic Aromatic Substitution: Fluorination and Iodination of Benzene
5.9K
Bromination and chlorination of aromatic rings by electrophilic aromatic substitution reactions are easily achieved, but fluorination and iodination are difficult to achieve. Fluorine is so reactive that its reaction with benzene is difficult to control, resulting in poor yields of monofluoroaromatic products. To address this, Selectfluor reagent is used as a fluorine source in which a fluorine atom is bonded to a positively charged nitrogen.
