Construction of a redox-active metal-organic framework with an octanuclear lithium one-dimensional building block

A stable lithium metal-organic framework, constructed using a redox-active N,N,N ',N '-tetrakis(4-carboxyphenyl)-1,4-phenylenediamine linker and Li8 cluster-based one-dimensional rod secondary building unit, exhibits good stability and reversible redox activity. The Li8-MOF, which can be oxidized by AgNO3, has the potential to function as an electrochromic device, thereby advancing the development of smart MOF materials. We have synthesized a stable redox-active lithium-organic framework, constructed by Li8 cluster-based one-dimensional rod secondary building unit, demonstrating good stability, reversible redox activity, and can function as an electrochromic device.
