摘要：

In this work, a novel synthesis approach of gold nanohybrid materials (Au/SH-OPPs) is demonstrated using the thiol-functionalized organic porous polymers (SH-OPPs) as a support by a combination of hyper-cross-linking and molecular templating of functionalized bottlebrush copolymers. HAuCl4 as the gold source is in situ reduced to produce Au nanoparticles based on the strong action of gold with the thiol groups. The monodispersed Au nanoparticles are anchored on the SH-OPPs with the small average particle size (3.0 +/- 1.0 nm) and the high loading about 18%. Moreover, the resultant Au/SH-OPPs exhibit excellent catalytic performance for the selective oxidation of benzyl alcohol.
