Guest-Induced Structural Transformation and Its Effect on the Redistribution of the Surface Confined Combinatorial Libraries

With the aim of better understanding the dynamic covalent chemistry and host–guest interaction at the liquid/solid interface, the Schiff base reaction was employed as a medium to investigate the distribution/redistribution of the dynamic covalent library (DCL) toward the presence of surface. In addition, coronene is used as a guest molecule to observe the guest-induced structural transformation at the liquid/solid interface. It is found that introduction of hydroxyl group which can form intra- and inter-molecular hydrogen bond significantly changes the response of DCL toward both surface and guest molecules at the interface. With the aid of surface introduction of the coronene as guest can significantly amplify a specific product.
