Clip-off Chemistry: Design and Synthesis of New Materials via Programmable Disassembly of Reticular Materials

Objective

Historically, innovations in synthetic methods and reactions have changed the way scientists think about designing and synthesizing materials and molecules. Indeed, novel synthetic methods not only unlock access to previously unattainable structures, but also inspire new concepts as to how we design and build materials to address global social, economic and industrial needs. The project that I propose here, CLIPOFF-CHEM, centers on the demonstration of a novel synthetic methodology that I have named Clip-off Chemistry. Unlike most state-of-the-art synthetic approaches, which use bottom-up strategies to link atoms and molecules through the formation of new bonds, Clip-off Chemistry is based instead on the selective cleavage of existing bonds in reticular materials, providing precise spatial control over bond cleavage. In reticular materials, this cleavage can be programmed to enable the synthesis of limitless materials varying by composition (from organic to metal-organic), dimensionality (from 3-D to 0-D) and size-scale (from macro- to nanoscale). Accordingly, in CLIPOFF-CHEM, I will employ clip-off synthesis to prepare a diverse collection of new materials and molecules, including new 3-D metal-organic frameworks (MOFs), low-dimensional (2-D and 1-D) materials, organic polymers, metal-organic polyhedra (MOPs), complexes and macrocycles. Our work will encompass 1) synthesis of the reticular material precursors (MOFs, COFs and MOPs) that incorporate non-cleavable and cleavable (alkene/alkyne) groups in precise positions of their structures; and 2) cleavage of alkene/alkyne groups through ozonolysis to produce the targeted materials. As the resultant products will be novel, we will also endeavor to identify and characterize any unprecedented structural or functional properties of them. I believe that CLIPOFF-CHEM will provide the global scientific community with an innovative methodology for the design and synthesis of new functional molecules and materials.
