Covalent Organic Frameworks

Covalent Organic Frameworks (COFs) are crystalline porous polymeric materials comprised of light weight organic struts connected by covalent linkages. The reticulation of COFs into the thermodynamically favored crystalline products is generally achieved by exploiting reversible processes called dynamic covalent chemistry. By linking such molecular building blocks via strong covalent bonds to crystalline open scaffold materials, our synthetic toolbox has expanded significantly to create materials with an unprecedented level of control over chemistry, structure and porosity. Today a variety of binding patterns, structures and topologies of COFs are known. The Thomas group develops novel COF materials for a range of applications, from catalysis, photo- and electrocatalysis to energy storage devices.
