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. [ABSTRACT FROM AUTHOR]
