Thermodynamic study of the interaction between 5,10,15,20-tetrakis-(N-methyl-4-pyridyl)porphyrin tetraiodine and sodium dodecyl sulfate

Interactions between cationic surfactants and 5,10,15,20-tetrakis(4-sulfonatophenyl)porphyrin tetrasodium salt as seen by electric conductometry and spectroscopic techniques

“…The occurrence of a higher hydrogen ion concentration lead to a water structure-breaking and, consequently, the effect of the dehydration of surfactant tails upon micellization is less significant for the entropy change. It should also be noted that the thermodynamics of micellization of C 12 TAB, in the presence of porphyrin, is different from that recently reported related with an homologous anionic surfactant (the sodium dodecyl sulfate) in the presence of a cationic porphyrin (5,10,15,20-tetrakis-(N-methyl-4-pyridyl)porphyrin tetraiodine) [40].…”

Self-assembly and photoconductivity of binary porphyrin nanostructures of meso -tetrakis(4-sulfonatophenyl)porphine and Co(III) meso -tetra(4-pyridyl)porphine chloride

“…Water-soluble porphyrins are well-suited for studying the properties of self-assembled nanostructures because the self-assembly can be conveniently controlled by changing the properties of the medium such as the pH [6][7][8]. Formation of a stable assembly can be explained by the contribution of electrostatic interactions, van der Waals forces, hydrogen bonds, axial coordination, and π-π interactions [9][10][11][12][13][14][15][16]. Shellnutt´s group progressed in the understanding of the morphology of self-assembled porphyrin nanostructures using different methods for studying the properties of porphyrins and metalloporphyrins [6,17,18].…”

Effect of [C n mim][Br] Based Ionic Liquids on the Aggregation Behavior of Tetradecyltrimethylammonium Bromide in Aqueous Medium

“…At ambient conditions, properties of an aqueous surfactant solution depend on the identity of the surfactant along with its concentration in the solution. One way to modify the physicochemical properties of a given aqueous surfactant solution is to use external means, such as changes in temperature, pressure and/or addition of variety of modifiers, including co-solvents, co-surfactants, electrolytes, polar organics and nonpolar organics [4][5][6][7][8][9][10][11][12][13][14][15].…”
