Molecular containers are specialized structures designed to encapsulate other molecules. They are often made from organic compounds and can form stable, cage-like shapes that trap guest molecules inside. This property allows them to be used in various applications, including drug delivery and catalysis. These containers can selectively bind to specific molecules, making them useful in fields like chemistry and materials science. Researchers study molecular containers to understand their interactions and improve their efficiency in capturing and releasing substances, which can lead to advancements in areas such as nanotechnology and biomedical engineering.
