Electron spectroscopy on the charge transfer complex [(7-amino-2,4 dimethyl-1,8 naphthyridine) (TCNQ)] (TCNQ = 7,7',8,8'-tetracyanoquinodimethane)

Abstract

Reflection electron energy loss spectroscopy (REELS) and optical reflectivity measurements have been used to characterize in the valence energy region the dielectric behavior of 7-amino-2,4 dimethyl-1,8 naphthyridine and of the charge transfer complex formed by this compound and the 7,7',8,8'-tetracyanoquinodimethane (TCNQ). The effects of the charge transfer interaction on the core energy levels have been investigated by comparing the line shape of the carbon and nitrogen Is core photoelectron peaks of the electron-donor and electron-acceptor molecules and of the charge transfer complex formed by them.
