Three dimensional inverse opal(IO) structure provide unique characteristics in high inner surface area, uniform pore size, large pore volume and periodic regularity. While UV-curable urethane acrylate prepolymer provide inert and stable physical property, only a few studies has been reported on the IO as a reactive membrane and there is a limitation for decorating with various catalysts. To expand the promising applications, another functional group for generating new chemical bond with target catalysts has to be exposed over entire inner IO surface. Here, we introduce Cu-catalyzed alkyne-azide cycloaddition for introducing catalyst on the IO and fabricate optimal clickable IO membrane by adjusting the colloidal nanoparticle size and the ratio between prepolymer and functional azide nomomer. To evaluate the catalytic performance, we will discuss quantitative oxidation test of alcohol by passing through TEMPO decorated IO membrane.
