CORONAND Meaning and
Definition
-
A coronand is a chemical compound that belongs to the class of macrocyclic compounds, specifically cyclic polyethers. It is characterized by the presence of one or more crown ether moieties within its structure. Crown ethers are a type of cyclic polyether that typically contain oxygen atoms as coordinating sites. The word "coronand" is derived from the Latin "corona," meaning crown.
Coronands have a unique structural arrangement in which the crown ether units form a ring-like structure, resembling a crown. Due to their cyclic nature, coronands possess a central cavity, or binding pocket, which enables them to selectively coordinate with metal ions or other guest species.
The synthesis of coronands often involves the cyclization of linear precursors via bridging groups to form the macrocyclic structure. This process results in the creation of a well-defined cavity suitable for hosting guest molecules or as a recognition site for metal ions. The size and shape of the coronand cavity can be tailored by adjusting the number and type of crown ether units used, allowing for fine-tuning of its binding properties.
Coronands find extensive applications in various fields, including supramolecular chemistry, catalysis, and molecular recognition. Their ability to selectively bind metal ions has been utilized in the design of sensors, molecular switches, and drug delivery systems. Furthermore, coronands have been studied for their potential use in ion separation, electrochemical devices, and as building blocks for functional materials.
