Técnicas de caracterização para investigar interações no nível molecular em filmes de Langmuir e Langmuir-Blodgett (LB)
(Sociedade Brasileira de Química, 2005-06-01)
This paper discusses fundamental concepts for the characterization of Langmuir monolayers and Langmuir-Blodgett (LB) films, with emphasis on investigations of material properties at the molecular level. By way of illustration, ...

Langmuir and Langmuir-Blodgett (LB) films of tetrapyridyl metalloporphyrins
(Elsevier B.V., 2008-07-15)
We report on the formation of Langmuir films of 5,10,15,20-tetra(4-pyridyl) 21H,23H-porphine,hereafter named tetrapyridyl porphyrins with distinct central ions (2H(+), Zn(2+), Cu(2+), Ni(2+)). The films were characterized ...

Estudos sobre complexos de Európio em Filmes de Langmuir e Langmuir -Blodgett
(Universidade Federal de São Paulo, 2022-11-21)
O objetivo desse trabalho foi estudar e reunir o conhecimento a respeito dos complexos de Európio em filmes de Langmuir e Langmuir Blodgett e apresentar o panorama desse contexto. O estudo foi dividido em duas etapas, a ...
Preparation and characterization of Langmuir-Blodgett films of 16-membered azobenzocrown ether with naphthalene residue
(Elsevier B.V. Sa, 2009-11-01)
Langmuir and Langmuir-Blodgett films of 16-membered azobenzocrown ether with naphthalene residue were prepared and characterized. The Langmuir monolayers were successfully transferred to form LB films onto solid substrates. ...

The use of Langmuir-Blodgett films of a perylene derivative and polypyrrole in the detection of trace levels of Cu2+ ions
(Elsevier B.V., 2005-01-03)
Langmuir films of a tetracarboxylic perylene derivative and polypyrrole display condensed surface pressure isotherms that are shifted when Cu2+ ions are added to the ultrapure water subphase. These films were transferred ...
Langmuir and Langmuir–Blodgett films of low-bandgap polymers
(2018-08-01)
Low-bandgap conjugated polymers have provided a considerable increase in organic photovoltaic efficiencies, however, an understanding of class-specific nanostructures, necessary to further improve device qualities, remains ...
Filmes de Langmuir e Langmuir-Blodgett de lipídios contendo pectinase
(Universidade Federal de São Paulo (UNIFESP), 2021)
In this work, we incorporated the enzyme pectinase into Langmuir monolayers of phospholipid acid dimyristoyl phosphatidic (DMPA) and transferred it to solid supports by the Langmuir-Blodgett (LB) technique. We also combine ...
