Orthogonally Reactive Diblock Copolymers Utilizing Alkyne and Isothiocyanate Groups

摘要

The monomer 4-isothiocyanato styrene (ITS) was synthesized and in combination with trimethyl((4-vinylphenyl)ethynyl)-silane (TMVES) polymerized under controlled radical polymerization conditions resulting in orthogonally reactive block copolymers. These were employed in the preparation of covalently bound layer-by-layer thin films allowing for sequential control of each layer deposited. A precise control of the internal film at the nanometer scale was achieved.
