(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2022-01-19)
This work aimed at the synthesis of porphyrins: meso-tetra(3-pyridyl)porphyrin (3-H2TPyP), meso-tetra [(3-
pyridyl)-chlor-(2,2'-bipyridyl)-palladium(II) ]porphyrin (3-Pd(bpy)TPyP), meso-tetra[(3-pyridyl)-chloro-(1,10-

Dual Emission of a Novel (P,N) Re-I Complex: A Computational and Experimental Study on [P,N-{(C6H5)(2)(C5H4N)P}Re(CO)(3)Br]
(American Chemical Society, 2015)
The spectroscopic, electrochemical, and photophysical properties of the new complex [P,N-{(C6H5)(2)(C5H4N)-P}Re(CO)(3)Br] are reported. The UV-vis spectrum in dichloromethane shows an absorption maximum centered at 315 rim ...
Distant ultrafast energy transfer in a trimetallic {Ru-Ru-Cr} complex facilitated by hole delocalization
(Royal Society of Chemistry, 2017-01)
Multi-metallic complexes based on {Ru-Cr}, {Ru-Ru} and {Ru-Ru-Cr} fragments are investigated for their light-harvesting and long-range energy transfer properties. We report the synthesis and characterization of ...
Oxygen-Insensitive Aggregates of Pt(II) Complexes as Phosphorescent Labels of Proteins with Luminescence Lifetime-Based Readouts
(American Chemical Society, 2018-07)
The synthesis and photophysical properties of a tailored Pt(II) complex are presented. The phosphorescence of its monomeric species in homogeneous solutions is quenched by interaction with the solvent and therefore absent ...
Intra- vs inter-molecular electron transfer processes in C[sbnd]N bond forming reactions. Photochemical, photophysical and theoretical study of 2′-halo-[1,1′-biphenyl]-2-amines
(Pergamon-Elsevier Science Ltd, 2016-12)
N-Arylation reaction is obtained when 2′-halo-[1,1′-biphenyl]-2-amines are irradiated in basic medium. On the basis of photochemical, photophysical experiments and computational studies we propose that carbazoles are formed ...
Disentangling the photophysics of DNA-stabilized silver nanocluster emitters
(American Chemical Society, 2016-10-28)
It has been already established that DNA-silver fluorophores present two intense absorption bands, one in the visible and the other in the UV spectral region, and that the excitation of both bands produces a common ...
Femtosecond Charge-Injection Dynamics at Hybrid Perovskite Interfaces
(Wiley VCH Verlag, 2017-09)
With a power conversion efficiency (PCE) exceeding 22 %, perovskite solar cells (PSCs) have thrilled photovoltaic research. However, the interface behavior is still not understood and is a hot topic of research: different ...
