This poster presents our recent progress in the synthesis of cylindrical molecular brushes with tunable and ultrahigh grafting density (up to 1.4 side chains per backbone carbon) by accelerated CuAAC coupling-onto strategy. Two kinds of polymer backbone (polycarbonate and polymethacrylate with two or three pendant azido groups) and various alkynyl-terminated SCs with different compositions and molecular weights, including ay-PMA, ay-PS, ay-PEO, ay-P<i>t</i>BA-<i>b</i>-PS, and ay-PDMA, were applied to synthesize molecular brushes with different properties. Moreover, the comparison of the dimensions of molecular brushes with different grafting density was also performed by AFM using the same test condition. These molecular brushes could be potentially applied in releasing guest molecule.
