Layered compounds assembled from molybdenum disulfide single-layers and alkylammonium cations

Intercalation compounds AxMoS2 have been obtained by restacking aqueous MoS2 dispersions in the presence of A-alkylammonium cations (A=R4N+ or R(CH3)3N+). Varying the experimental conditions, the negative charge of the MoS2 single-layers in the dispersions can be modified, which allows to control the content and packing geometry of the A guest layers in the resulting intercalation compounds. The value of the negative charge kept on the MoS2 host layers of the intercalation compounds determines the degree of in-layer distortion of their Mo sublattice.
