Ionic Association

Ionic Association

The ionic association is the association of oppositely charged ions in an electrolyte solution to form ion pairs. Bjerrum defined ion pairs as two oppositely charged ions whose electrostatic attraction exceeds the thermal energy of the system, typically expressed as 2kT. Electrostatic attraction depends on ionic charge, separation distance, and the dielectric constant of the medium. Thermal energy, represented by kT, reflects the tendency of ions to move independently due to molecular motion.

π Electron Effects on Chemical Shift: Overview

π Electron Effects on Chemical Shift: Overview

An applied magnetic field causes loosely bound π-electrons in organic molecules to circulate, producing a local or induced diamagnetic field over a large spatial volume. As the molecules tumble in solution, the field generated by π-electrons in spherical substituents results in a zero net field. However, the net field generated by π-electrons in non-spherical substituents is not zero. The effect of this induced field depends on the orientation of the molecule with respect to B0,...

Intermolecular Forces

Intermolecular Forces

Atoms and molecules interact through bonds (or forces): intramolecular and intermolecular. The forces are electrostatic as they arise from interactions (attractive or repulsive) between charged species (permanent, partial, or temporary charges) and exist with varying strengths between ions, polar, nonpolar, and neutral molecules. The different types of intermolecular forces are ion–dipole, dipole–dipole, hydrogen bonds, and dispersion; among these, dipole–dipole, hydrogen...

Van der Waals Interactions

Atoms and molecules interact with each other through intermolecular forces. These electrostatic forces arise from attractive or repulsive interactions between particles with permanent, partial, or temporary charges. The intermolecular forces between neutral atoms and molecules are ion–dipole, dipole–dipole, and dispersion forces, collectively known as van der Waals forces.

Area of Science:

Physical Chemistry
Materials Science
Computational Chemistry

Background:

Atomic-based ion-π interactions (A-IPIs) are crucial in molecular recognition, catalysis, and materials assembly.
Limited elemental variety restricts the tunability of traditional A-IPIs.

Purpose of the Study:

To introduce and investigate superatomic-based ion-π interactions (S-IPIs) using superatoms instead of atoms.
To explore the potential of S-IPIs for expanding the scope of ion-π interactions.

Main Methods:

First-principles calculations were employed to study S-IPIs.
Superatoms were modeled interacting with graphene fragments as substrates.

Main Results:

Superatoms maintain structural stability and exhibit electronegativity-driven charge transfer in S-IPIs, analogous to A-IPIs.
Interaction strength and chemical reactivity of S-IPI complexes are tunable by modifying superatom type and electronic configuration.
S-IPIs effectively expand the traditional ion-π interaction paradigm.

Conclusions:

S-IPIs offer a novel approach to designing and tuning ion-π interactions.
This work paves the way for fundamental research and applications utilizing artificial elemental superatoms in ion-π systems.
