Organização supramolecular da ftalocianina de cobalto(II) e seu efeito na oxidação do aminoácido cisteína

Abstract: Recebido em 13/2/09; aceito em 9/9/09; publicado na web em 23/2/10 SUPRAMOLECULAR ORGANIZATION OF COBALT (II) PHTHALOCYANINE ON THE PATHWAY OF CYSTEINE OXIDATION. The interest in the chemistry of cobalt (II) tetrasulfonated phthalocyanine (PcTsCo) comes mainly from its macrocycle-ligand structure combined with their special chemical characteristics, such as high solubility, well-defined redox reactions and remarkable optical absorption in the visible region. In this work, we use layer-by-layer technique in ord… Show more

“…2,11 In the LbL method, the self-assembly process is governed by individual immobilization of positively and negatively charged polyelectrolytes, which allow for design and control of the thickness and structural morphology aspects. 2,[11][12][13][14] In the context of nanoscience, constitutional dynamic chemistry (CDC) concepts 15 confer the means to interpret and control functional supramolecular entities, since dynamic character such as functional recognition and self-organization must be directly involved on the molecular level. 16 Cyclodextrin (CD) molecules are defined as macrocyclic oligosaccharides composed of six (a), seven (b) or eight (g) linked glucosyl units organized in a cone shape, which show a lipophilic central cavity and hydrophilic outer surface.…”

“…9, 2011 Moreover, the association to micelles leads to an increase of substrate specificity. [48][49][50] Apart from the chemical catalysis, the photoactivation of porphyrin/lipid aggregates has also been described. 18 The photocatalysis process conducted by porphyrins is based on the generation of excited states of these molecules, followed by electronor energy-transfer reactions able to trigger the chemical reactions of interest (Figure 3).…”

“…Enquanto para a formação de um filme LB, o substrato é imerso verticalmente, nos filmes LS a imersão se dá com o substrato na horizontal. A grande desvantagem da deposição horizontal é a falta de controle da quantidade de material adsorvido na superfície do substrato sólido e, logo, não há uma garantia de que toda a superfície foi recoberta com a monocamada [58,61,64].…”

“…Também permite um controle sobre a arquitetura supramolecular dos filmes. Além disso, a gama muito maior de materiais pode ser utilizados na produção de filmes automontados, já que o equilíbrio de crescimento do filme automontado é governado, na maioria dos casos, pela atração entre cargas elétricas opostas [15,58,60,64].…”
