Phloxine B as a Probe for Entrapment in Microcrystalline Cellulose

Autor: Enrique San Román, Paulo Duarte, Diana P. Ferreira, Isabel Ferreira Machado, Luís Filipe Vieira Ferreira, Hernan B. Rodríguez

Publikováno v: Molecules, Vol 17, Iss 2, Pp 1602-1616 (2012)

The photophysical behaviour of phloxine B adsorbed onto microcrystalline cellulose was evaluated by reflectance spectroscopy and laser induced time-resolved luminescence in the picosecond-nanosecond and microsecond-millisecond ranges. Analysis of the

Structural, Morphological, Optical and Photocatalytic Properties of Y, N-Doped and Codoped TiO₂ Thin Films

Autor: Zeineb, Hamden, David, Conceição, Sami, Boufi, Luís Filipe, Vieira Ferreira, Soraa, Bouattour

Publikováno v: Materials

Pure TiO2, Y-N single-doped and codoped TiO2 powders and thin films deposited on glass beads were successfully prepared using dip-coating and sol-gel methods. The samples were analyzed using grazing angle X-ray diffraction (GXRD), Raman spectroscopy,

Photophysical Studies of a New Water Soluble Indocarbocyanine Dye Adsorbed onto Microcrystalline Cellulose and beta-Cyclodextrin

Autor: Anabela Oliveira, Luís Filipe Vieira Ferreira, Paulo Almeida, David Conceição, Diana Ferreira, Reda El-Shishtawy

Publikováno v: Molecules, Vol 18, Iss 5, Pp 5648-5668 (2013)
Molecules
Volume 18
Issue 5
Pages 5648-5668

A water-soluble indocarbocyanine dye was synthesized and its photophysics were studied for the first time on two solid hosts, microcrystalline cellulose and β-cyclodextrin, as well as in homogeneous media. The inclusion of the indocarbocyanine moiet

A study of N,N′-dicarboxyalkylthiacarbocyanines as cyanine direactive dyes covalently bound to cellulose

Autor: Anabela Oliveira, Luís Filipe Vieira Ferreira, Paulo Almeida, Renato Boto

Publikováno v: Dyes and Pigments. 48:71-84

The synthesis of N,N ′-dicarboxyalkylthiacarbocyanines and their spectroscopic properties before and fixation to microcrystalline cellulose are described. Fixation yields were determined by FTIR spectroscopy, giving an alternative to the classical

Singlet oxygen generation ability of squarylium cyanine dyes

Autor: Anabela Oliveira, Luís Filipe Vieira Ferreira, Paulo Almeida, Lucinda Vaz Reis, Paulo Santos

Publikováno v: Journal of Photochemistry and Photobiology A: Chemistry. 160:159-161

The quantum yields for singlet oxygen generation of several squarylium cyanine dyes derived from benzothiazole, benzoselenazole and quinoline, displaying absorption within the so-called “phototherapeutic window” (600–1000 nm), were determined,
