Low energy electron beam irradiation promoted selective cleavage of surface furoxan

Abstract

The results of a study of a low energy electron-beam irradiation induced cleavage reaction of surface localized furoxan, by using X-ray photoelectron spectroscopy (XPS), Fourier transform-infrared (FT-IR) spectroscopy, and near-edge X-ray absorption fine structure (NEXAFS) spectroscopy were reported. The synchrotron radiation source was utilized for XPS analysis of the furoxan imine layers, at the Pohang Accelerator laboratory. The thiol-modified gold substrates were reacted with aziridine for the surface polymerization. The results suggested that the selective chemical reaction that was triggered by electron impact on the surface is the same as that occurring in the gas phase.
