Competitive ultrafast electron and proton transfer reactions within titania and silica mesoporous materials

Gil, Michael; Organero, Juan Angel; Navarro Ruiz, María Teresa; Corma Canós, Avelino; Douhal, Abderrazzak (American Chemical Society, 2012-07-26)

[EN] We report on UV-visible absorption and emission and ultrafast emission dynamics of 7-hydroxyquinoline (7HQ) encapsulated within titania-doped silicates (mesoporous and unstructured) and purely TiO2 nanomaterials. When ...
Confined Photodynamics of an Organic Dye for Solar Cells Encapsulated in Titanium-Doped Mesoporous Molecular Materials

Ziólek, Marcin; Martín, Cristina; Navarro Ruiz, María Teresa; García Gómez, Hermenegildo; Douhal, Abderrazzak (2011-04-12)

[EN] A triphenylamine dye (TPC1) encapsulated in titanium-doped mesoporous silica structures as alternative materials for dye-sensitized solar cells has been studied by means of stationary absorption and emission as well ...
Deciphering the photobehaviour of ensemble and single crystals of Zr-based ITQ MOF composites

Caballero-Mancebo, Elena; Moreno Rodríguez, José María; Corma Canós, Avelino; DÍAZ MORALES, URBANO MANUEL; Cohen, Boiko; Douhal, Abderrazzak (Elsevier, 2021-01-01)

[EN] Understanding the interactions that govern the photophysical behaviour of Metal-organic frameworks (MOFs) and their composites is paramount for their photochemical and photonic applications. In this work, we report ...
Exploring the Photodynamics of a New 2D-MOF Composite: Nile Red@Al-ITQ-HB

Caballero-Mancebo, Elena; Cohen, Boiko; Moreno Rodríguez, José María; Corma Canós, Avelino; DÍAZ MORALES, URBANO MANUEL; Douhal, Abderrazzak (American Chemical Society, 2018-02)

[EN] In this work, we unravel the photodynamics of Nile Red (NR) interacting with Al-ITQ-HB nanostructure, a new layer-type metal-organic framework (MOF) with potential catalytic and photonic applications. Steady-state ...
Femto-to nanosecond photodynamics of Nile Red in metal-ion exchanged faujasites

di Nunzio, Maria Rosaria; Caballero-Mancebo, Elena; Martin, Cristina; Cohen, Boiko; Navarro Villalba, Mª Teresa; Corma Canós, Avelino; Douhal, Abderrazzak (Elsevier, 2018-01-15)

[EN] We report on the photodynamics of Nile Red (NR) interacting with faujasite (NaY)-type zeolites having different Na/Al ratios and charge balancing metals (Li+, Mg2+, and Cs+) in dichloromethane (DCM) suspensions. The ...
How does the Surface of Al-ITQ-HB 2D-MOF Condition the Intermolecular Interactions of an Adsorbed Organic Molecule?

Caballero-Mancebo, Elena; Moreno Rodríguez, José María; Corma Canós, Avelino; DÍAZ MORALES, URBANO MANUEL; Cohen, Boiko; Douhal, Abderrazzak (American Chemical Society, 2018-06-13)

[EN] In this work, we unravel how the two-dimensional Al-ITQ-4-heptylbenzoic acid (HB) metal-organic framework (MOF) changes the interactions of Nile red (NR) adsorbed on its surface. Time-resolved emission experiments ...
Interrogating the Behaviour of a Styryl Dye Interacting with a Mesoscopic 2D-MOF and Its Luminescent Vapochromic Sensing
