Summary
Researchers enhanced organic-inorganic hybrid materials by tuning intermolecular forces. This strategy effectively increased the phase-transition temperature (Tc) for improved energy storage and sensor applications.
Area of Science:
- Materials Science
- Solid-State Chemistry
- Crystallography
Background:
- Organic-inorganic hybrid phase-transition materials are promising for energy storage and sensors due to their adaptable structures and ease of synthesis.
- A key challenge is effectively increasing their phase-transition temperature (Tc).
Purpose of the Study:
- To develop a strategy for regulating intermolecular interactions to enhance the phase-transition temperature (Tc) of organic-inorganic hybrid materials.
- To synthesize and characterize novel hybrid materials with tunable Tc values.
Main Methods:
- Synthesized three bismuth chloride-based hybrid compounds using azetidine, 3,3-difluoro azetidine, and 3-carboxyl azetidine as organic components.
- Investigated crystal structures, including one-dimensional chain and zero-dimensional structures.
- Analyzed intermolecular forces using Hirshfeld surface and 2D fingerprint analyses.
Main Results:
- Successfully synthesized three compounds with distinct phase-transition temperatures: 234 K, 256 K, and 350 K.
- Demonstrated that varying organic components effectively modulated intermolecular interactions, including hydrogen bonds.
- Confirmed the correlation between modulated intermolecular forces and enhanced Tc values.
Conclusions:
- The strategy of regulating intermolecular interactions by selecting appropriate organic components is effective for increasing the phase-transition temperature (Tc).
- The synthesized materials show potential for advanced applications in energy storage and sensors.
- This work provides a pathway for designing high-Tc organic-inorganic hybrid materials.

Whether solid, liquid, or gas, a substance's state depends on the order and arrangement of its particles (atoms, molecules, or ions). Particles in the solid pack closely together, generally in a pattern. The particles vibrate about their fixed positions but do not move or squeeze past their neighbors. In liquids, although the particles are closely spaced, they are randomly arranged. The position of the particles are not fixed—that is, they are free to move past their neighbors to...

02:39Phase Transitions: Melting and Freezing
12.4K
Heating a crystalline solid increases the average energy of its atoms, molecules, or ions, and the solid gets hotter. At some point, the added energy becomes large enough to partially overcome the forces holding the molecules or ions of the solid in their fixed positions, and the solid begins the process of transitioning to the liquid state or melting. At this point, the temperature of the solid stops rising, despite the continual input of heat, and it remains constant until all of the solid is...

Intermolecular forces are attractive forces that exist between molecules. They dictate several bulk properties, such as melting points, boiling points, and solubilities (miscibilities) of substances. Molar mass, molecular shape, and polarity affect the strength of different intermolecular forces, which influence the magnitude of physical properties across a family of molecules.
Temporary attractive forces like dispersion are present in all molecules, whether they are polar or nonpolar. They...

The internal energy of a substance—the total kinetic energy of all its molecules and the potential energy of their associated forces—depends on the strength of the intermolecular forces in the condensed phases and the pressure exerted on the substance. The internal energy of a substance is the highest in the gaseous state, the lowest in the solid state, and intermediate in the liquid state. Phase transitions are caused by changes in physical conditions, such as temperature and...

Intermolecular forces (IMF) are electrostatic attractions arising from charge-charge interactions between molecules. The strength of the intermolecular force is influenced by the distance of separation between molecules. The forces significantly affect the interactions in solids and liquids, where the molecules are close together. In gases, IMFs become important only under high-pressure conditions (due to the proximity of gas molecules). Intermolecular forces dictate the physical properties of...
