Multiple stimuli-responsive nanoparticles that could respond to visible-light, pH and host-guest interactions were fabricated by self-assembly of tetra-ortho-methoxy-substituted azobenzene (mAzo) functionalized poly(dimethylaminoethyl methacrylate) (PDMAEMA) (PDMAEMA-mAzo), which was synthesized...

A series of tetraalkyl azobenzene-m-tetracarboxylates was synthesized and characterized by polarized-light optical microscopy (POM), differential scanning calorimetry (DSC) and by UV-visible spectroscopy investigations. The dyes were readily obtained from esterification reactions of azobenzene-m...

Application of stimuli-responsive bioactive molecules is an attractive strategy due to use for target special tissues and cells. Here, we reported synthesis of an azo-linker, 2,2’-dimethoxyl-4,4’-dihydroxymethylazobenzene (mAzo), which was more effectively recognized and cleaved by reducing gl...

In this work, we have successfully synthesized azobenzene nanocluster from azobenzene molecules through a bottom-up approach. The synthesized azobenzene nanocluster shows beautiful green fluorescence and well dispersed in aqueous medium. Interestingly, the photoswitchable property of azobenzene ...

Intrinsic healable polymers are materials capable of repairing itself through its chemical nature, in order to improve stability and durability and to restore the lost functionalities or properties.In this study, azobenzene (AZO) moieties were incorporated into a previously reported bridged sils...

The effect of alumina on the catalytic performance of Pt-Sn/Al2O3 catalysts in the green synthesis of secondary amines by N-alkylation of amines with alcohols based on the borrowing hydrogen strategy was investigated. N-alkylation of aniline with benzyl alcohol to produce N-phenylbenzylamine was...

The reflectance spectrum of solid MeReO3(trans-4-styrylpyridine) shows a long-wavelength band (λmax = 342 nm) with vibrational structure. This band is assigned to an intraligand transition of the coordinated styrylpyridine. In solution (e.g. CH2Cl2) the complex largely dissociates into MeReO3 a...

Leishmaniasis are globally widespread parasitic diseases which often leads to death if left untreated. Currently available drugs present different drawbacks, so there is an urgent need to develop new, safe and cost-effective drugs against leishmaniasis. In this study we tested a small library of...

The scintillation properties of trans-stilbene crystals grown for the first time by application of the solution growth technique to the scale of 10 cm are reported. Measurements of the scintillation light output, pulse shape discrimination, and neutron detection efficiency were made with sets of...

Stilbenes and its various derivatives have been studied in different branches of science, because of their unique properties such as fluorescence, phosphorescence, photophysical, photochrome, photochemical and various biological properties. Despite of these potentials, one of the problems of sti...

We start with literature data on gas to solvent partition of trans-stilbene, as log K, for 52 solvents. The log K values can be converted into corresponding water to solvent partitions, as log P, through the stilbene gas to water partition coefficient, and lead, with four additional equations, t...

Scintillator geometry affects light-collection efficiency (LCE) and, as a consequence, detector-performance metrics that depend on LCE, such as particle-type identification. This work compares the neutron–gammapulse-shape discrimination (PSD) performance of two trans-stilbene crystals of differ...

The paper reports results on growth and characterization of the first deuterated analog of the trans-stilbene crystal. The high optical quality stilbene-d12 single crystal was grown by application of the solution technique using specially synthesized raw material and an aromatic solvent (anisole...

The neutron light-output response from quasi-monoenergetic neutrons was measured for a Ø5.08 × 5.08 cm trans-stilbene and a Ø5.08 × 5.08 cm small-molecule organic glass scintillator. Quasi-monoenergetic neutrons were isolated from a time-of-flight measurement of a Cf-252 spontaneous fission so...

(±)-iso-Amarine can be conveniently resolved via 1:1 salt formation with either hand of mandelic acid. Enantiopure iso-amarine can be acetylated and hydrolysed to give enantiopure 1,2-diamino-1,2-diphenylethanes.

Several oxidative approaches namely thiocyanation of aromatic compounds, epoxidation of alkenes, amidation of aromatic aldehydes, epoxidation of α, β-unsaturated ketones, oxidation of sulfides to sulfoxides and sulfones, bayer-villeger reaction, bromination and iodation of aniline and phenol d...

Cinnamic acid (CA) and methyl cinnamate (MC) have attracted interest of researchers because of their broad therapeutic functions. Here, we investigated the interaction of CA and MC with bovine serum albumin (BSA) at pH 3.5, 5.0, and 7.4 using fluorescence spectroscopy, differential scanning nano...

The frequent use of synthetic pesticides to control Aedes aegypti population can lead to environmental and/or human contamination and the emergence of resistant insects. Linalool and methyl cinnamate are presented as an alternative to the synthetic pesticides, since they can exhibit larvicidal, ...

Chiral 2-arylcarboxylic acid esters are important intermediates in preparation of enantioenriched 2-arylpropionic acids type Non-steroidal anti-inflammatory drugs (NSAIDs). Enantiomer separation of 2-arylcarboxylic acid esters is crucial for evaluation of the asymmetric synthesis efficiency and ...

β-amino acids are widely used in drug research, and S-3-amino-3-phenylpropionic acid (S-APA) is an important pharmaceutical intermediate of S-dapoxetine, which has been approved for the treatment of premature ejaculation. Chiral catalysis is an excellent method for the preparation of enantiopur...
