Interaction of cationic water-soluble meso-tetrakis(4-N-methylpyridiniumyl)porphyrin (TMPyP) with ionic and nonionic micelles: aggregation and binding
(WORLD SCI PUBL CO INC, 2008)
The equilibrium of meso-tetrakis(4-N-methylpyridiniumyl)porphyrin (TMPyP) in aqueous solution in the presence of surfactants was studied by optical spectroscopic techniques and SAXS (small angle X-ray scattering). Anionic ...
On the localization of water-soluble porphyrins in micellar systems evaluated by static and time-resolved frequency-domain fluorescence techniques
(ELSEVIER SCIENCE BV, 2008)
Fluorescence quenching of meso-tetrakis-4-sulfonatophenyl (TPPS4) and meso-tetrakis-4-N-methylpyridil (TMPyP) porphyrins is studied in aqueous solution and upon addition of micelles of sodium dodecylsulfate (SDS), ...

Estudo da formação e isolamento de heterocomplexos constituídos pela combinação entre 4,4’,4’’,4’’’- tetracarboxiftalocianina de ferro ou 4,4’,4’’,4’’’- tetrassulfoftalocianina de ferro e tetrakis (N-metil- 4-piridil) porfirina de ferro e aplicação em filmes LbL”
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2016-01-04)
The great
interest in supramolecular assemblies between porphyrins and phthalocyanines has
growing lately due to the enhancement on chemical and physical properties compared to
individual units. Ionic assemblies with ...
Effect of interaction with micelles on the excited-state optical properties of zinc porphyrins and J-aggregates formation
(Elsevier BVAmsterdam, 2013-08)
This work reports on the photophysical properties of zinc porphyrins meso-tetrakis methylpyridiniumyl (Zn2+TMPyP) and meso-tetrakis sulfonatophenyl (Zn2+TPPS) in homogeneous aqueous solutions and in the presence of sodium ...
Imidazolium-based ionic liquids as stabilizers for electrode modification with water-soluble porphyrin
(Facultad de Medicina y Ciencia, 2019)
The water-soluble porphyrin, known as 5,10,15,20-tetrakis(1-methyl-4-pyridyl)porphyrin (TMPyP), was successfully stabilized onto a carbon paste electrode (CP) by covering up the TMPyP-modified surface with a layer of ionic ...
Effects of environment on the photophysical characteristics of mesotetrakis methylpyridiniumyl porphyrin (TMPyP)
(Elsevier BVAmsterdam, 2011-09)
Porphyrins are an important class of organic molecules, with interesting linear and nonlinear optical properties given mainly by their extended π-conjugation structure. Their photophysical properties can be greatly affected ...
