Ferrocene: an exotic building block for supramolecular assemblies

Area of Science:

• Supramolecular Chemistry
• Organometallic Chemistry

Background:

• Ferrocene (Fc) is a well-established organometallic complex with diverse applications.
• Emerging research highlights Fc's utility as a fundamental component in supramolecular chemistry.

Purpose of the Study:

• To review the design principles and development of ferrocene-based supramolecular assemblies.
• To showcase the role of Fc in the formation and function of these assemblies.

Main Methods:

• Review of existing literature on ferrocene in supramolecular chemistry.
• Analysis of Fc's molecular properties (shape, size, hydrophobicity, redox behavior) and their impact on assembly formation.

Main Results:

• Ferrocene's unique structural and electronic features (e.g., "ball bearing" property, tunable hydrophobicity) are ideal for host-guest complexation and intramolecular interactions.
• Fc serves as a key building block for diverse supramolecular structures, including molecular receptors, metal-organic assemblies, polymers, gels, and nanoparticle assemblies.

Conclusions:

• Ferrocene's integration into supramolecular chemistry is a rapidly growing field with significant potential.
• Fc-based assemblies offer tailored properties and programmable functions for applications in materials and biological sciences.
