Abstract

Various embodiments relate to a method for producing a metal-organic framework (MOF) having a desired redox conductivity and including redox-active linkers, having ω-alkyl-ferrocene groups, via de novo solvothermal synthesis. Various embodiments relate to a metal-organic framework (MOF) linker comprising an ω-alkyl-ferrocene group. Various embodiments relate to a metal-organic framework (MOF), having a first plurality of redox-active linkers, each having an ω-alkyl-ferrocene group. The MOF according to various embodiments, may further have one or more redox-inactive linkers. Various embodiments relate to materials, apparatuses, and components that include the MOF according to various embodiments. For example, various embodiments relate to thin-films, bulk powders, or electrodes.
