We propose a combination of different techniques to obtain the absorption cross-section spectra triplet- and singlet-states in porphyrin-like molecules. Two extensions Z-scan technique are employed (pulse train white-light Z-scan) together with absorbance spectroscopy laser flash photolysis. This approach allowed us investigate features excited-states meso-tetrakis (methylpyridiniumyl) porphyrin (TMPyP) that revealed influence solvents on vibronic structuration transitions assigned...
Hybrid van der Waals heterojunctions based on organic polymers and 2D materials have emerged as a promising solution for developing more efficient optoelectronic devices. Herein, we investigated the charge transfer (CT) dynamics at interface of poly[3-hexylthiophene-2,5-diyl] (P3HT) polymer MoS2 monolayer. A global picture P3HT/MoS2/SiO2 heterojunction was elucidated from photoluminescence (PL) spectroscopy fluorescence lifetime decay profile. Rapid interfacial between P3HT indicated by...
We report experimental and theoretical studies of the two-photon absorption spectrum two nitrofuran derivatives: nitrofurantoine, (1-(5-nitro-2-furfurilideneamine)-hidantoine) quinifuryl, 2-(5′-nitro-2′-furanyl)ethenyl-4-{N-[4′-(N,N-diethylamino)-1′-methylbutyl]carbamoyl} quinoline. Both molecules are representative a family 5-nitrofuran-ethenyl-quinoline drugs that have been demonstrated to display high toxicity various species transformed cells in dark. determine cross-section for both...
Interaction between porphyrins and quantum dots (QD) via energy and/or charge transfer is usually accompanied by reduction of the QD luminescence intensity lifetime. However, for CdSe/ZnS-Cys water solutions, kept at 276 K during 3 months (aged QD), significant increase in addition meso-tetrakis (p-sulfonato-phenyl) porphyrin (TPPS4) has been observed this study. Aggregation storage provokes yield lifetime their luminescence. Using steady-state time-resolved fluorescence techniques, we...
When graphene is deposited on a surface, and that free of any type molecules adsorbed its surface (air contaminant, polymer residue, <italic>etc.</italic>), the substrate influence minimal, characteristics are predominant.
