XPS analysis of nanocomposite Li2x−yMn1−xPS3(C13H11N2)y films

Intercalation of 9-aminoacridine (9AA: C13H10N2) in thin films of exfoliated Li2x−yMn1−xPS3 has been performed by means of a solution approach starting from the hydrochloride salt of the organic species (9AAHCl: C13H10N2·HCl). The resulting nanocomposite Li2x−yMn1−xPS3(C13H11N2)y films have been investigated by X-ray photoemission spectroscopy (XPS), at room temperature, in the regions of the Mn, P, S and Cl 2p, Li, C and N 1s and Mn 3p core levels. The XPS analysis has been also carried out on the 9-aminoacridine hydrochloride films whose XPS spectra have been compared with those of the Li2x−yMn1−xPS3(C13H11N2)y films to obtain information about the nature of the interaction between the guest species (9AAH+) and the matrix (Li2x−yMn1−xPS3−).
