The photoinduced hydrogen (or deuterium) detachment reaction of thiophenol (C(6)H(5)SH) or thiophenol-d(1) (C(6)H(5)SD) pumped at 243 nm has been investigated using the H (D) ion velocity map imaging technique. Photodissociation products, corresponding to the two distinct and anisotropic rings observed in the H (or D) ion images, are identified as the two lowest electronic states of phenylthiyl...

the highly substituted pyridine derivatives are found to exhibit diverse pharmacological activities. they are also emerged as potential medicinal leads in developing therapeutic agents for the treatment of various diseases. in this work, a series of 2-amino-3,5-dicarbonitrile-6-thio-pyridine derivatives have been synthesized at room temperature via one-pot, multi-component reaction of various a...

We here explore a kinetically controlled synthetic protocol for preparing solvent-solvable Au102(SPh)44 nanoclusters which are isolated from polydispersed gold nanoclusters by solvent extraction and size exclusion chromatography (SEC). The as-obtained Au102(SPh)44 nanoclusters are determined by matrix-assisted laser desorption ionization (MALDI) and electrospray ionization (ESI) mass spectromet...

Nonlinear optical Sum and Difference-Frequency spectroscopies are used to probe and model the surface of thiophenol-functionalised gold nanoparticles grafted on a Si(100) substrate through two different silanization procedures. By scanning the [980-1100 cm(-1)] infrared spectral range with the CLIO Free Electron Laser, ring deformation vibrations of adsorbed thiophenol are investigated. Quantit...

In this work, we present a study on the sensing of chemical molecules with Au nanoparticles coated ZnO film by employing photo-induced enhanced Raman scattering (PIERS) coupled to surface-enhanced (SERS). Moreover, interest coupling PIERS classical SERS (electromagnetic contribution) is achieve high sensitivity detection. our employed thiophenol molecule for its quality adsorption metals and sm...

While Fenton chemistry has long been known to play a role in inducing cellular stress, there recent renewed interest understanding its roles health and disease. Here we describe fluorogenic rhodamine-thiophenol probe, RTFt1, which applies both chelation recognition strategies sense the reactants, Fe(II) H2O2. RTFt1 undergoes 200-fold increase red fluorescence emission presence of After confirmi...
