A stable lithium metal-organic framework, constructed using a redox-active N , N , N ', N '-tetrakis(4-carboxyphenyl)-1,4-phenylenediamine linker and Li 8 cluster-based one-dimensional rod secondary building unit, exhibits good stability and reversible redox activity. The Li 8 -MOF, which can be oxidized by AgNO 3 , has the potential to function as an electrochromic device, thereby advancing the development of smart MOF materials.
