A new zinc (II) complex material [bis(salicylicaldehyde-trimethylol amino methane)Zn(II)] has been prepared and characterized by means of elemental analysis, IR spectra, molar conductivity and photoluminescence spectra. The results show that the O and N atoms interact with Zn atoms through coordination bonds. As a potential organic light-emitting material ( OLEDs), the surface electron state of zinc (II) complex material has been investigated using X-ray photoelectron spectroscopy (XPS) technology.
