INCORPORATION OF METHYLENE-BLUE IN NAY ZEOLITE AT CRYSTALLOGRAPHICALLY DEFINED POSITIONS

Communication: Nanoporous structures containing dye molecules have bee n found to have interesting nonlinear optical properties. The various methods used for the incorporation of the guests in the host lattice r esult in very different positioning of the guests relative to the host structure. Here, these methods are compared for the incorporation of Methylene Blue at crystallographically, non-random, positions. The pro cesses are examined using X-ray diffraction and Rietveld analysis.
