Dynamic combinatorial chemistry (DCC) is based on the principle that the thermodynamic composition of a dynamic library of molecules, that is, a library of which the components are held together either by noncovalent bonds or reversible covalent bonds, spontaneously changes upon the input of an external stimulus.[1] This can be either the addition of a target molecule, but also an alteration of the environment (pH, light, etc.). Ideally, the ...
