摘要: Abstract We prepared acetylenyl-terminated aromatic self-assembled monolayers (SAMs) of 1,4-diethynylbenzene on silver and gold. After the fabrication pendent acetylenyl SAMs, formation triazoles was performed via Cu(I)-catalyzed Huisgen 1,3-dipolar cycloaddition “click” chemistry. A density functional theory (DFT) calculation Raman frequencies showed good agreement with our experimental data to provide evidence triazole molecule. Our results indicated that chemistry could be successfully applied simple SAMs proximate ( 1 nm ) roughened gold surfaces. The reaction process monitored in real time by measuring intensity changes ν(C C)free band surface-enhanced scattering (SERS) spectra.
