Bioinspired core-bound polymeric micelles, based on hydrogen bonding and photo-crosslinking, of thymine have been prepared from poly(vinylbenzylthymine)-b-poly(vinylbenzyltriethylammonium chloride). The amphiphilic block copolymer was synthesized by 2,2-tetramethylpiperidin-1-oxylmediated living radical polymerization in water/ethylene glycol solution. Micelle characterization and critical micelle concentration measurements demonstrated that the hydrogen bonding of the attached thymine units stabilizes the micelles. Further, core-crosslinked polymeric micelles were formed by ultraviolet (UV) radiation showing that the stability of the micelle could be controlled by the UV crosslinking of the attached thymines.
