(Elsevier B.V., 2017)
Tetra-tert-butyl-cis,cis-3,7-dihydroxybicyclo[3.3.0]octa-2,6-diene-2,4-exo-6,8-exo-tetracarboxylate (I) and tetra-tert-butyl-cis,cis-3,7-dimethoxybicyclo[3.3.0]octa-2,6-diene-2,4-exo-6,8-exo-tetracarboxylate (II) were ...
Experimental and theoretical studies of the photophysics of 7-amino-3-phenyl-2H-benzo[b] [1,4]oxazin-2-one in homogeneous solvents and beta-cyclodextrin aqueous solutions
(Asoc Quimicos, Inst Quimico Sarria, 2015)
The photophysical behavior of 7-amino-3-phenyl-2H-benzo[b][1,4]oxazin-2-one was studied in organic solvents and in aqueous solutions of beta-cyclodextrin using steady-state fluorescence and computational chemistry methods. ...
Comparative esterification of phenylpropanoids versus hydrophenylpropanoids acids catalyzed by lipase in organic solvent media
(Pontificia Universidad Católica de Valparaíso, 2007)
Relationship between photo-physical and electrochemical properties of D--A compounds regarding solar cell applications. 1. Substituent type effect in photovoltaic performance
(SPRINGER, 2019)
Studying the electrochemical characteristics is an important step for determining interactions between molecules and the chemical environment. Moreover, the electrochemical evaluation of dyes is highly needed to establish ...
A novel type of organometallic 2-R-2,4-dihydro-1H-3,1-benzoxazine with R = [M(eta(5)-C5H4)(CO)(3)] (M = Re or Mn) units. Experimental and computational studies of the effect of substituent R on ring-chain tautomerism
(2019)
The syntheses, characterization, X-ray crystal structures, electrochemical properties and anticancer and antichagasic activities of the first examples of 2-substituted 2,4-dihydro-1H-3,1-benzoxazines with half-sandwich ...
Reaction of singlet molecular oxygen, O-2((1) Delta(g)), with the Cinchona tree alkaloids - Effect of absolute configuration on the total rate constant
(ELSEVIER SCIENCE, 2005-10-31)
Detection of O-2((1)Delta(g)) emission, lambda(max) = 1270 nm, following laser excitation and steady-state methods were employed to measure the total reaction rate constant, k(T), and the reactive reaction rate constant, ...
Photoexcited Nonadiabatic Dynamics of Solvated Push–Pull π-Conjugated Oligomers with the NEXMD Software
(American Chemical Society, 2018-06)
Solvation can be modeled implicitly by embedding the solute in a dielectric cavity. This approach models the induced surface charge density at the solute-solvent boundary, giving rise to extra Coulombic interactions. Herein, ...
Synthesis, spectroscopic and electrochemical characterization of copper(I) complexes with functionalized pyrazino[2,3-f]-1,10-phenanthroline

The present work reports the synthesis and spectroscopic and electrochemical characterization of homoleptic copper(l) complexes with substituted pirazino [2,3-f]-1,10-phenanthroline, RpplR', (R = H, Me, COOH or COOMe, and ...
Thermal and solvatochromic effects on the emission properties of a thienyl-based dansyl derivative
(Royal Soc Chemistry, 2020-08-04)
Environmental conditions have a profound effect on the photophysical behavior of highly conjugated compounds, which can be exploited in a large variety of applications. In this context, we use a combination of experimental ...
