The properties of the TMPyP cations in the materials were compared with those of other systems (solutions, colloids) characterized mainly by absorption and fluorescence spectroscopies. Linearly polarized absorption spectroscopy, X-ray diffraction (XRD), and fluorescence microscopy were used as well. Using appropriate layered silicate templates, applying the premodification of the inorganic component with hydrophobic alkylammonium surfactants, and selecting an appropriate method, one can prepare the materials of broadly variable spectral properties of the dye. The spectral variation takes place while preserving the photochemical activity of TMPyp.
