New electrophilic sulfur(VI) functional styrenic monomers allowed multiple orthogonal post-functionalization reactions of styrene copolymers. Styrene monomers containing fluorosulfate and catechol cyclic sulfate functional handles were synthesized and copolymerized with styrene, as well as vinylbenzyl azide and silyl ether protected vinylphenol. The copolymers were sequentially functionalized with fluorescent dyes at room temperature without deprotection. Covalent attachment of dyes to the polymers was verified by GPC UV-Vis detection.
