Abstract: A two-dimensional metal-organic framework (2D MOF) includes a first transition metal M1 and a second transition metal M2. The first transition metal and the second transition metal are different and are coupled by a linker group L to yield a two-dimensional metal-organic framework alloy having a formula M1xM21-xL, where 0<x<1. Each transition metal is dispersed uniformly throughout the 2D MOF. The 2D MOF is synthesized by combining a first transition metal precursor, a second transition metal precursor, and a linker; agitating the solution; and heating the solution to yield a crystalline two-dimensional metal-organic framework alloy.

Abstract: Forming a two-dimensional polymeric sheet includes translating a portion of a flexible substrate through a first liquid precursor to coat the portion of the flexible substrate with the first liquid precursor, thereby yielding a precursor-coated portion of the flexible substrate. The precursor-coated portion of the flexible substrate is translated through an interface between the first liquid precursor and a second liquid precursor, thereby reacting the first liquid precursor on the precursor-coated portion of the flexible substrate with the second liquid precursor to yield a polymer-coated portion of the flexible substrate.

Abstract: Synthesizing a metal-organic-framework includes combining a first solution and a second solution to yield a synthetic medium. The first solution typically includes a solvent, an inhibitor, a metal capping agent, a ligand, and a metal source, and the second solution typically includes a deprotonating agent and a buffer. The metal and the ligand are reacted in the synthetic medium to yield a two-dimensional metal-organic-framework in the form of a nanosheet, and the two-dimensional metal-organic-framework is removed from the synthetic medium. The two-dimensional metal-organic framework has an aspect ratio of at least 300 or at least 1000.
