A series of flexible MOFs (PCN‐605, PCN‐606, and PCN‐700) are synthesized and applied to reversible bromine encapsulation and release. The chemical stability of these Zr‐MOFs ensures the framework's integrity during the bromine adsorption, while the framework's flexibility allows for structural adaptation upon bromine uptake to afford stronger host–guest interactions and therefore higher bromine adsorption capacities. The flexible MOFs act as bromine‐nanocontainers which elongate the storage time of volatile halides under ambient conditions. Furthermore, the bromine pre‐adsorbed flexible MOFs can be used as generic bromine sources for bromination reactions giving improved yields and selectivities under ambient conditions when compared with liquid bromine.

柔性锆MOF作为溴-纳米容器用于环境条件下的溴化反应

合成了一系列灵活的MOF（PCN-605，PCN-606和PCN-700），并将其应用于可逆溴的封装和释放。这些Zr-MOF的化学稳定性可确保框架在溴吸附过程中的完整性，而框架的灵活性则可根据溴的吸收进行结构调整，以提供更强的主体-客体相互作用，从而提高溴的吸附能力。柔性MOF用作溴-纳米容器，可延长挥发性卤化物在环境条件下的存储时间。此外，与液体溴相比，溴预吸附的柔性MOF可用作溴化反应的通用溴源，可在环境条件下提高收率和选择性。
