Dynamic-covalent/combinatorial chemistry (DCC) has become an increasingly important tool in supramolecular chemistry, allowing the high-yielding formation of organic molecular architectures from simple precursors in minimal steps and under thermodynamic control. Some of the most widely used dynamic covalent bonds include imines, boronic esters, disulfides, and alkenes and alkynes, each of which has been used to form covalent molecular capsules under thermodynamic control.
