Synthesis of Porphyrins with ABAB Symmetry from Dipyrromethanes as Potential Phototherapeutic Agents

Autor: María E. Pérez, Milena B. Boarini, María Elisa Milanesio, Edgardo N. Durantini

Publikováno v: The 24th International Electronic Conference on Synthetic Organic Chemistry.

Asymmetrically meso-substituted porphyrins were synthesized with ABAB symmetry patterns. The approach required the formation of dipyrromethanes, which were obtained from the condensation of an aldehyde (pentafluorobenzaldehyde, 4-nitrobenzaldehyde or

Electrochemical polymerization of EDOT modified Phthalocyanines and their applications as electrochromic materials with green coloration, and strong absorption in the Near-IR

Autor: Gustavo M. Morales, Edgardo N. Durantini, Miguel Gervaldo, Luis Otero, María Elisa Milanesio, Estefanía Baigorria, Claudia Alejandra Solis

Publikováno v: Electrochimica Acta. 213:594-605

Electropolymerization by cyclic voltammetry of both Cu and Zn EDOT modified phthalocyanines is described. Polymeric films were successfully formed on Pt, ITO, and Pt containing a previously deposited layer of PEDOT. Based on electrochemical and spect

Synthesis, spectroscopic properties and photodynamic activity of Zn(II) phthalocyanine-polymer conjugates as antimicrobial agents

Autor: Estefanía Baigorria, María Elisa Milanesio, Edgardo N. Durantini

Publikováno v: European Polymer Journal. 134:109816

Conjugates of Zn(II) phthalocyanine to chitosan (CS) and polyethylenimine (PEI) were synthetized through the following stages: first a phthalonitrile substituted by a (carbomethoxy)phenoxy group (Pn 1) was obtained by nucleophilic aromatic substituti

Publikováno v: Chemistry (Weinheim an der Bergstrasse, Germany). 24(22)

A novel chlorin derivative (TPCF20-NMe2) was synthesized as a syn adduct of a pyrrolidinefused chlorin carrying an C-linked N,N-dimethylaminophenyl residue. The absorption spectrum of TPCF20-NMe2 was basically identical to that of TPCF20 in N,N-dimet
