Incorporation of methylene blue in NaY zeolite at crystallographically defined positions

Nanoporous structures containing dye molecules have been found to have interesting nonlinear optical properties. The various methods used for the incorporation of the guests in the host lattice result 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 processes are examined using X‐ray diffraction and Rietveld analysis.
