Phenanthroline intercalation into molybdenum disulfide

The interaction of MoS 2 single-layer dispersion with 1,10-phenanthroline has been studied over the pH range 0–11. Only protonated phenanthroline initiates flocculation of dispersion and formation of intercalation compounds. Two intercalated phases containing respectively 0.31–0.35 and 0.1 mol of phenanthroline per mol MoS 2 have been isolated. In the first one (interlayer spacing c = 14.92–15.56 A) the planar organic species are inclinated with respect to MoS 2 layers. In the second one ( c = 9.7 A) these moieties are oriented parallel to the layers.
