Dynamic mechanical and dielectric relaxations in poly(dibenzyl itaconate) and poly(diethylphenyl itaconate)
(ELSEVIER SCI LTD, 2000)
Dynamic mechanical and dielectric behaviour of poly(dibenzyl itaconate), and poly(diethylphenyl itaconate) were studied. The study was performed by determining the components of the complex relaxation modulus E* and the ...
Steric hindrance and electronic effects of sulfonatepropyl chain on gold center. An experimental and DFT study
(Elsevier Science Sa, 2017-12)
Density Functional Theories (DFT) methods were applied to describe the catalytic effect of a series of sulfonated NHC gold(I) complexes In order to explain the experimental results obtained in the hydration of phenylacetylene ...
Layered double hydroxide nanoparticles customization by polyelectrolyte adsorption: mechanism and effect on particle aggregation
(Elsevier Science, 2017-11)
Adsorption of polyelectrolytes (PEs) is a common strategy for stabilizing nanoparticles and customizing their properties. Although scarcely explored for layered double hydroxide nanoparticles (LDH-NPs), it can be used to ...
INFLUENCE OF THE STERIC HINDRANCE OF ANCILLARY LIGANDS IN Ru-BASED COMPLEXES APPLIED IN METATHESIS OF CINNAMYL ALCOHOL AND CINNAMYL ACETATE
(Soc Brasileira Quimica, 2020-01-01)
Cinnamyl alcohol (AC) and cinnamyl acetate (ACM) were used as substrates in olefin metathesis reactions catalyzed by RuCl2(PCy3)(2)(=CHPh), first-generation Grubbs catalyst-G1, and RuCl2(PCy3)(H(2)Mes)(= CHPh), second-generation ...
Pros and cons of coating layered double hydroxide nanoparticles with polyacrylate
(Elsevier Science, 2019-05)
Preventing the aggregation of layered double hydroxide nanoparticles (LDH-NP) and producing additional functionality are two important objectives for their applications as drug nanocarriers, among others. Adsorption of ...
Selective Sulfenylative Desulfonylation or Decarbalkoxylation of -Sulfonyl Malonates with DABCO or Bu3N: Reactivity and Conformational Analysis
(TAYLOR & FRANCIS INC, 2010)
The study on reactivity of several -substituted -sulfonyl malonates toward 1,4-diazabicyclo[2.2.2]octane (DABCO) and Bu3N is described. The reactivity with DABCO revealed the possible competition between decarbalkoxylation ...
Photoinduced one-electron oxidation of Aromatic Selenides: Effect of the structure on the reversible dimerization reaction
(American Chemical Society, 2018-05)
The photochemical one-electron oxidation of alkyl aryl selenides was studied by means of laser flash photolysis (355 nm). Quenching of the sensitizers in their excited state leads to selenide radical cation in the presence ...
On the photochemical properties of the organometallic trans cyrhetrenyl chalcone (E). Deceleration of the photoisomerization and quenching of the luminescence effected by the photogenerated cis isomer (Z)
(2018)
The photoprocesses of two organometallic chalcone complexes: one trans (E) [(eta(5)-C5H4C(O)CH = CH-Ph) Re(CO)(3)], (1a), and the other functionalized with a macrocyclic trans (E) [(eta(5)-C5H4C(O)CH = CH-4-benzo-15-crown-5) ...
