koordinaatiokiteitä

Koordinaatiokiteitä, known in English as coordination polymers or metal-organic frameworks (MOFs), are a class of crystalline materials formed by the coordination of metal ions or clusters with organic ligands. These ligands act as linkers, bridging the metal centers to create extended one-, two-, or three-dimensional networks. The structure of these materials is highly dependent on the choice of metal ions and organic linkers, allowing for a vast diversity of architectures and properties.

The key characteristic of koordinaatiokiteitä is their porosity. The intricate network structures often contain voids or channels that can encapsulate guest molecules. This porosity, combined with the tunable nature of their composition, makes them attractive for various applications. These include gas storage and separation, catalysis, sensing, drug delivery, and even electronics.

The synthesis of koordinaatiokiteitä typically involves solvothermal or hydrothermal methods, where metal salts and organic ligands are reacted in a solvent under elevated temperature and pressure. The resulting crystalline materials can then be characterized using techniques such as X-ray diffraction, gas adsorption, and spectroscopy to determine their structure and properties. Research in this field focuses on designing new koordinaatiokiteitä with specific functionalities and improving their stability and scalability for practical applications.
