Journal ArticleDOI
Optical Gas Sensing of Ammonia and Amines Based on Protonated Porphyrin/TiO2 Composite Thin Films
Pedro Castillero,Javier Roales,Tânia Lopes-Costa,Juan R. Sanchez-Valencia,Angel Barranco,Agustín R. González-Elipe,José M. Pedrosa +6 more
TL;DR: The monocationic porphyrin has been found to be more sensible than its tetracationic counterpart and there was an observed decrease of the emission fluorescence intensity in consecutive cycles of exposure and recovery due to the formation of ammonium chloride inside the film.
Journal ArticleDOI
Optical detection of amine vapors using ZnTriad porphyrin thin films
Javier Roales,José M. Pedrosa,María G. Guillén,Tânia Lopes-Costa,Sara M. A. Pinto,Mário J. F. Calvete,Mariette M. Pereira +6 more
TL;DR: In this paper, the authors used a tripodal porphyrin, 1,3-di[5-(3-hydroxyphenyl)-10,15,20-(triphenyl)porphyrin]-2-(5-3-hybrid-polymorphic-polygonal-polycyclic) porphrin (ZnTriad), to detect amines through spectroscopy.
Journal ArticleDOI
A lanthanide MOF immobilized in PMMA transparent films as a selective fluorescence sensor for nitroaromatic explosive vapours
Francisco G. Moscoso,José Domingues de Almeida,Ahmad Sousaraei,Tânia Lopes-Costa,Ana M. G. Silva,Juan Cabanillas-Gonzalez,Luís Cunha-Silva,José M. Pedrosa +7 more
TL;DR: In this paper, a highly selective and sensitive luminescent sensor based on simply mixing a Tb(III)-based luminescence Metal-Organic Framework with polymethyl-methacrylate enabling to detect sub-ppb range of nitroaromatic vapours, properly.
Journal ArticleDOI
Luminescent MOF crystals embedded in PMMA/PDMS transparent films as effective NO2 gas sensors
Francisco G. Moscoso,José Domingues de Almeida,Ahmad Sousaraei,Tânia Lopes-Costa,Ana M. G. Silva,Juan Cabanillas-Gonzalez,Luís Cunha-Silva,José M. Pedrosa +7 more
TL;DR: In this article, a fluorescent NO2 gas sensor using the metal-organic framework (MOF) Tb(BTC) (BTC = benzene-1,3,5-tricarboxylate) as an active material is reported.
Journal ArticleDOI
Free-Base Carboxyphenyl Porphyrin Films Using a TiO2 Columnar Matrix: Characterization and Application as NO2 Sensors
Javier Roales,José M. Pedrosa,María G. Guillén,Tânia Lopes-Costa,Pedro Castillero,Angel Barranco,Agustín R. González-Elipe +6 more
TL;DR: The improved stability of films made with m-TCPP suggests this molecule as the best candidate among the set of porphyrins for the fabrication of NO2 sensors, revealing good sensing capabilities in all cases.
