Dynamic bond exchange

Reactions used in DCvC must generate thermodynamically stable products to overcome the entropic cost of self-assembly. The reactions must form covalent linkages between building blocks. Finally, all possible intermediates must be reversible, and the reaction ideally proceeds under conditions that are tolerant of functional groups elsewhere in the molecule. WebBond exchange in polymer networks has received much attention as a route to recycling and circularity of materials which are typically not reprocessable. In addition, the presence of dynamics bonds can lead to large impacts on the transport of guest molecules relevant for membrane separations, ion conducting electrolytes, and thermal transport.
