CageMoleküle

Cage molecules are a class of supramolecular compounds characterized by their distinctive three-dimensional cage-like structure. These molecules are formed through the self-assembly of smaller building blocks, often organic ligands, around a central metal ion or cluster. The resulting structure encloses a cavity or void within the cage, which can then encapsulate guest molecules. The size and shape of this cavity can be tuned by altering the dimensions and arrangement of the constituent building blocks.

The formation of cage molecules is a prime example of host-guest chemistry. The host is the cage molecule itself, and the guest is the molecule that becomes trapped within its cavity. This encapsulation can be driven by various non-covalent interactions, including hydrogen bonding, van der Waals forces, and electrostatic interactions. The stability and selectivity of guest binding are crucial aspects of cage molecule research.

The applications of cage molecules are diverse and span multiple scientific disciplines. In chemistry, they are employed as catalysts, often by stabilizing reactive intermediates or directing reaction pathways within their confined environment. They can also serve as molecular sensors, exhibiting changes in properties like fluorescence or color upon binding to specific analytes. In medicine, cage molecules are being investigated for drug delivery, where they can protect therapeutic agents from degradation and target their release to specific sites in the body. Furthermore, their ability to isolate and stabilize transient species makes them valuable tools for fundamental research in various fields of chemistry and physics.
