Journal ArticleDOI
Hybrid sol-gel channel waveguide patterning using photoinitiator-free materials
TL;DR: In this paper, an organic-inorganic sol-gel glass channel waveguide was constructed by ultraviolet photopolymerization of material synthesized from the precursor methacryloxypropyltrimethoxysilane using a pulsed 248nm excimer laser.
Journal ArticleDOI
Novel tetradentate chelators derived from 3-hydroxy-4-pyridinone units: synthesis, characterization and aqueous solution properties
Andreia Leite,Ana M. G. Silva,Ana Nunes,Mariana Andrade,Carla de Sousa,Luís Cunha-Silva,Paula Gameiro,Baltazar de Castro,Maria Rangel +8 more
TL;DR: In this article, the synthesis and characterization of three novel tetradentate ligands (T1, T2 and T3) based on 3-hydroxy-4-pyridinone chelating units are described.
Journal ArticleDOI
Antibacterial activity of naphthyl derived bis-(3-hydroxy-4-pyridinonate) copper(II) complexes against multidrug-resistant bacteria.
Andreia Leite,Lucinda J. Bessa,Ana M. G. Silva,Paula Gameiro,Baltazar de Castro,Maria Rangel +5 more
TL;DR: The complex Cu(naph1pp)2 shows the highest antibacterial activity, including against multidrug-resistant isolates, nonetheless, being more active against Gram-positive than Gram-negative bacteria.
Journal ArticleDOI
Synthesis and coordination studies of 5-(4′-carboxyphenyl)-10,15,20-tris(pentafluorophenyl)porphyrin and its pyrrolidine-fused chlorin derivative
José Domingues de Almeida,André M. N. Silva,Susana L.H. Rebelo,Luís Cunha-Silva,Maria Rangel,Baltazar de Castro,Andreia Leite,Ana M. G. Silva +7 more
TL;DR: In this paper, a synthetic strategy to obtain 5-(4′-carboxyphenyl)-10,15,20-tris(pentafluorophenyl)porphyrin and its pyrrolidine-fused chlorin derivative was developed by the 1,3-dipolar cycloaddition of a carbomethoxyphensyl substituted porphyrin with an azomethine ylide, followed by hydrolysis under thermal acidic conditions.
Journal ArticleDOI
Distinctive EPR signals provide an understanding of the affinity of bis-(3-hydroxy-4-pyridinonato) copper(II) complexes for hydrophobic environments.
Maria Rangel,Andreia Leite,André M. N. Silva,Tânia Moniz,Ana Nunes,M. João Amorim,Carla Queirós,Luís Cunha-Silva,Paula Gameiro,John Burgess +9 more
TL;DR: The use of EPR spectroscopy is put forward to assess the affinity of copper(ii) complexes for a hydrophobic environment and also to obtain indirect information about the lipophilicity of the ligands and similar EPR silent complexes.
