Synthesis and characterization of a novel series of meso (nitrophenyl) and meso (carboxyphenyl) substituted porphyrins
(Sociedade Brasileira de Química, 2000-10-01)
As porfirinas aniônicas 5,10,15-tris(4-carboxifenil), 20-mono(2-nitrofenil) porfirina (1), 5,10(ou 15)-bis(4-carboxifenil), 15(or 10),20-bis(2-nitrofenil)porfirina (2) and 5-mono(4-carboxifenil), 10,15,20-tris(2-nitrofen ...
Chitosan as a Bioadhesive Agent Between Porphyrins and Phospholipids in a Biomembrane Model
(AMER SCIENTIFIC PUBLISHERS, 2011)
Porphyrins are currently used in photodynamic therapy as photosensitizers. In this paper we studied the interaction of two charged porphyrins, 5, 10, 15, 20-mesotetrakis(N-metyl-4-pyridyl) porphyrin, (TMPyP/chloride salt) ...
Characterization of electrodes chemically modified with Mn(III) porphyrin/polypyrrole films as catalytic surfaces for an azo dye
(Soc Porphyrins & Phthalocyanines, 2006-01-01)
In this study we describe the electrochemical behavior of 5,10,15,20-tetrakis(2'-aminophenylporphyrin)manganese(III) chloride supported on a glassy carbon electrode, as well as the electrochemical preparation and ...
Stabilization Of Meso-tetraferrocenyl-porphyrin Films By Formation Of Composite With Prussian Blue
(World Sci Pub Co IncHackensack, 2017)
Electrochemical Generation of Porphyrin-Porphyrin and Porphyrin-C60 Polymeric Photoactive Organic Heterojunctions
(Pergamon-Elsevier Science Ltd., 2014-04)
Photoactive organic-organic interfaces are formed by electrochemical synthesis. The generation of porphyrin/porphyrin and porphyrin/C60 heterojunctions over indium tin oxide electrodes by successive electropolymerization ...
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 ...
Dextrin-microencapsulated porphyrin - Luminescent properties
(BLACKWELL PUBLISHING, 2008)
Photophysical properties of porphyrins in aqueous solutions are strongly affected by aggregation. One possible solution to this problem is to encapsulate the porphyrin into polymeric spheres, to provide an environment where ...
Surface Porphyrins Metalate with Zn Ions from Solution
(American Chemical Society, 2015-12)
Controlling the metalation of surface porphyrins is a critical process in porphyrin-based devices. Indeed, surface porphyrins are known to metalate in ultrahigh vacuum from codeposited metal atoms or substrate atoms; ...
New porphyrins tailored as biodiesel fluorescent markers
(ELSEVIER SCI LTD, 2011)
This work reports the synthesis, characterization, and evaluation of new porphyrins tailored to become biodiesel fluorescent markers. The compounds were obtained by the synthetic modification of the commercially available ...
Characterization and catalytic activity of 2,6-dichlorophenyl substituted iron(III) porphyrin supported on silica gel and imidazole propyl gel
(Elsevier B.V., 1997-03-07)
In this work we have made use of the study of the interaction between Fe(TDCPP)(+) and the axial ligands OH- and imidazole in order to help characterize the heterogenized catalysts Fe(TDCPP)SG and Fe(TDCPP)IPG through ...
