Phenanthroline intercalation into molybdenum disulfide

Abstract

The interaction of MoS2 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 MoS2 have been isolated. In the first one (interlayer spacing c = 14.92–15.56 Å) the planar organic species are inclinated with respect to MoS2 layers. In the second one (c = 9.7 Å) these moieties are oriented parallel to the layers.
