Description
Summary:	Layered organic–inorganic hybrid nanocomposite, containing an organic dye in an inorganic interlayer was prepared using Evan's Blue (EB) as a guest in Mg–Al layered double hydroxide inorganic host by a self-assembly technique, with the Mg–Al ratio of 4 in the mother liquor at pH=7.5. Powder X-ray diffractogram shows that the basal spacing of the Mg–Al layered double hydroxide with nitrate as the intergallery anion expanded from 8 to about 20 Å to accommodate the EB anion, for the formation of the Mg–Al layered double hydroxide–EB layered organic–inorganic hybrid nanocomposite (MAEN). Formation of such a material is useful, for example for controlled release purposes of dye for slow dyeing process.
