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.

First claim

What is claimed is:

1. A method for producing a metal-organic framework (MOF) having a desired redox conductivity and comprising redox-active linkers, each having ω-alkyl-ferrocene groups, the method comprising:
combining, in a solvent comprising ZrOCl 2 , one or more redox-active linkers and one or more redox-inactive linkers in a ratio sufficient to provide the MOF with the desired redox conductivity,
wherein at least one of the one or more redox-active linkers comprise the following formula:

R being a C 1 to C 24 alkyl;
wherein at least one of the one or more redox-inactive linkers comprise the following formula:

and
wherein the produced MOF comprises the following formula:
Zr 6 O 4 (OH) 4 [F c x NR 1-x ] 6 ;

wherein Fc represents the plurality of redox-active linkers,
wherein NR represents the one or more redox-inactive linkers, and
wherein x is from 2 to 100.

2. The method according to claim 1 , wherein the MOF displays a maximum electron conductivity of about 122 mS cm −1 .

3. The method according to claim 1 , wherein the MOF displays crystallographic and electrochemical stability upon a number of redox cycles greater than 1,000.
