==Significance== | |||
Since the proposal of this class of materials, metal-organic framework have been proven to support many roles. Applications to gas storage, analytical chemistry and (bio)sensors, batteries and fuel cell technology, separation science, synthesis and catalysis, harvesting of water from dry (low humidity) air, water purification and environmental remediation, capture/destruction of harmful agents, energy conversion and storage, hydrogen generation, food | |||
safety, and drug delivery & diagnostics/therapy have been demonstrated<ref>https://www.nobelprize.org/uploads/2025/10/advanced-chemistryprize2025.pdf</ref>. | |||
Highlighting the significance is the fact [[Proteopedia:Hot_News| three chemists doing seminal work in this field were awarded the Nobel Prize in Chemistry in 2025]]. The structure featured here played a key role in establishing this field. | |||
