چکیده انگلیسی


• Spectral investigation of TMPyP/reduced-charge montmorillonite systems was performed
• Impact was given on a photofunctionality of prepared hybrid systems
• The studied systems are promising and suitable candidates for the utilization as a photofunctional materials

Spectral properties of tetracationic organic dye, meso-tetrakis(N-methylpyridinium-4-yl) porphyrin adsorbed on layered silicate templates of various layer charge were investigated. A series of reduced charge Nanocor montmorillonites was used as host matrices. The study primarily focuses on the influence of the layer charge on the emission characteristics and photoactivity of prepared materials. Usually, adsorption of dyes such as porphyrins leads to significant changes in their spectral characteristics with the main goal being the preservation of their photoactivity. The spectral changes can be explained in terms of e.g. structural changes (flattening, protonation), as well as molecular aggregation. Hence, the aim of this study is to clarify the way to influence the spectral properties and the subsequent photoactivity of incorporated molecules via a strategy of appropriate combination of a photoactive component with specific inorganic templates.
