Abstract
Using the copper-catalyzed azidealkyne cycloaddition click reaction, a library of triazole amphiphiles with a variety of functional polar heads and hydrophobic or superhydrophobic tails was synthesized. The amphiphiles were evaluated for their ability to stabilize small Au nanoparticles, and, at the same time, serve as templates for nanocasting porous SiO2. One of the Au@SiO2 materials thus prepared was found to be a highly active catalyst for the Au nanoparticle-catalyzed regioselective hydroamination of alkynes.
