Several MOFs are evaluated as adsorbents of anthropogenic N₂O emissions, the third most abundant greenhouse gas, through complimentary experimental and DFT analysis. N₂O activation in M₂(dobdc) MOFs is also studied. 

Fluorine is an increasingly common substituent in pharmaceuticals and agrochemicals because it improves the bioavailability and metabolic stability of organic molecules. Fluorinated gases represent intuitive building blocks for the late-stage installation of fluorinated groups, but they are generally overlooked because they require the use of specialized equipment. We report a general strategy for handling fluorinated gases as benchtop-stable solid reagents using metal-organic frameworks (MOFs). Gas-MOF reagents are prepared on gram-scale and used to facilitate fluorovinylation and fluoroalkylation reactions. Encapsulation of gas-MOF reagents within wax enables stable storage on the benchtop and controlled release into solution upon sonication, which represents a safer alternative to handling the gas directly. Furthermore, our approach enables high-throughput reaction development with these gases. 

Abstract Carbon capture and sequestration (CCS) from industrial point sources and direct air capture are necessary to combat global climate change. A particular challenge faced by amine‐based sorbents—the current leading technology—is poor stability towards O₂. Here, we demonstrate that CO₂chemisorption in γ‐cylodextrin‐based metal–organic frameworks (CD‐MOFs) occurs via HCO₃⁻formation at nucleophilic OH⁻sites within the framework pores, rather than via previously proposed pathways. The new framework KHCO₃CD‐MOF possesses rapid and high‐capacity CO₂uptake, good thermal, oxidative, and cycling stabilities, and selective CO₂capture under mixed gas conditions. Because of its low cost and performance under realistic conditions, KHCO₃CD‐MOF is a promising new platform for CCS. More broadly, our work demonstrates that the encapsulation of reactive OH⁻sites within a porous framework represents a potentially general strategy for the design of oxidation‐resistant adsorbents for CO₂capture.
