Highlights: [•] 9-aminoacridine intercalation was performed in thin films of exfoliated Li2x Mn1−x PS3. [•] Li2x−y Mn1−x PS3(C13H11N2) y and C13H11N2Cl film XPS spectra were investigated. [•] XPS spectra confirm that the 9-aminoacridine molecule is protonated in both films. [•] The interaction between 9AAH+ (guest) and Li2x−y Mn1−x PS3 − (host) is electrostatic. [•] Mn2+ in Li2x−y Mn1−x PS3(C13H11N2) y films is in the high spin state as in MnPS3. [ABSTRACT FROM AUTHOR]

Abstract: Manganese thiophosphate powders have been intercalated with sodium ions at two different intercalation times (150min and 180min) in order to evaluate the influence of this parameter on the dielectric properties of the obtained compounds labeled like Na2x Mn1−x PS3. In particular, dielectric permittivity measures have been carried out as a function of temperature (80K–350K) and frequency (20Hz to 1MHz) and compared with each other and with those of the pure matrix and of the Na2x Mn1−x PS3 compound corresponding to a 120min intercalation time. Both investigated compounds show a dielectric response characterized by a loss peak at low temperatures, by a strong dispersion at low frequency and at not very high temperatures and by a crossover frequency showing an Arrhenius temperature dependence in agreement with what already observed in Na2x Mn1−x PS3 (120min). The results have been also discussed in terms of ac conductivity, Maxwell–Wagner–Sillar (MWS) polarization, electrode polarization and dc conductivity and all the above cited features have been attributed to the Na+ ions which are, by their nature, hopping charge carriers that behave like jumping dipoles in their alternate motions and simultaneously show conducting characteristics resulting from their extended hopping over many sites. This attribution allows us to classify the analyzed sodium compounds like hopping charge carrier systems in which a greater Na intercalation time translates into a decrease in the loss peak intensity and an increase in the activation energy associated to the crossover frequency.

Abstract: Na0.88Mn0.56PS3compounds have been synthesized by starting from MnPS3 polycrystalline powders by means of a two-step cation-exchange process at a higher intercalation time than the one used for producing the literature reported Na0.62Mn0.69PS3 compounds. The obtained samples have been characterized by X-ray photoelectron spectroscopy (XPS). The resulting spectra of the so-synthesized compounds have been compared with those observed in Na0.62Mn0.69PS3 in our previous paper and similar electronic properties have been noted. In particular by XPS it has been shown that greater sodium content affects neither the core-level binding energies of the host matrix elements nor the type of link between Na+ and (Mn1−x PS3)−.
