چکیده مقاله:

Spectroscopic characterization of porphyrins interacting with different micelles has attracted the interest of many researchers in the last decades incorporation of porphyrins in micelles dramatically influences their aggregation mode [4]. Porphyrin aggregates studied by several techniques such as UV/vis absorption spectroscopy by observing spectral shifts in the Soret band from monomers to the red region (J-aggregates) or to the blue (H-aggregates); resonance light scattering (RLS) which displays enhancement of light scattering intensity due to aggregated forms, whereas the monomeric porphyrin does not show RLS effect. In this study an attempt is made to gain more insight into the nature of interaction of a watersoluble porphyrin with biological structure using simplest model for membrane in the aqueous solution of ionic micelle (SDS) [4].Interactions of the water soluble Cu (II) 5-(Hexadecyl pyridynium-4-yl)-10, 15, 20-tris (Butyl Pyridynium-4-yl) Porphyrin (CuMHxTB), with ionic micelle in aqueous solutions have been studied by optical absorption and resonance light-scattering (RLS) spectroscopy .The presence of three different species of Cu(II)MHxTB in anionic sodium dodecyl sulfate (SDS) solution has been demonstrated: free metalloporphyrin monomers, and metalloporphyrin-surfactant aggregates (at below the SDS critical micelle concentration (CMC)), micellized monomer(at upon the (CMC)).
