چکیده

The modular synthesis of a series of nitrogen-rich polydentate ligands that feature a common pincer-type framework is reported. These ligands allow for site-selective installation of palladium and platinum to give rise to bi- and trimetallic complexes that have d(8)-d(8) interactions.

Design of Highly Uniform Platinum and Palladium Nanoparticle Decoration on TiO2 Nanotube Arrays: An Efficient Anode to the Electro-Oxidation of Alcohols

We explore electro-catalytic properties of a system consisting of platinum and palladium nanoparticles dispersed over a nanotubular self-organized TiO2 matrix. These electrodes prepared by electroess and microemulsion of palladium and palladium nanoparticles on to TiO2 nanotubes, respectively. Titanium oxide nanotubes were fabricated by anodizing titanium foil in ethylene glycol (EG) fluoride-c...

Programmable self-assembly of homo- or hetero-metallomacrocycles using 4-(1H-pyrazolyl-4-yl)pyridine.

The dimetallic [M(2)(bpy)(2)(NO(3))(2)](NO(3))(2) moieties (M = Pd(II) or Pt(II)) react preferentially at the pyrazolyl end of the pyridyl-pyrazole ligand, giving rise to dimetallic corners. Subsequently, the dimetallic corner building blocks featuring two pyridine donors are coordinated by monometallic [M(bpy)(NO(3))(2)] moieties (M = Pd(II) or Pt(II)) to form homo- or hetero-metallomacrocycles.

Developing a CoMSIA model for inhibition of COX-2 by resveratrol derivatives

Design of selective cyclooxygenase-2 (COX-2) inhibitors is still a challenging task because of active site similarities between COX isoenzymes. To help with this issue, we tried to generate a 3D-QSAR (3 dimensional quantitative structure activity relationship) model that might reflect the essential features of COX-2 active sites. Compounds in a series of resveratrol derivatives inhibitors with ...

A Density Functional Theory Investigation of d8 Transition Metal(II) (Ni, Pd, Pt) Chloride Complexes of Some Vic-dioximes Derivatives

Herein, a theoretical study on the stability of some vic-dioxime complexes of Ni(II), Pd(II) and Pt(II) in gas and aqueous phases is reported. The DFT/M06/SDD and DFT/M06/6-31G+(d,p) levels of theory were adopted for the metal ions and for every other element respectively. Structural analyses of investigated complexes have revealed square planar geometries stabilized by two O–H⋯Cl hydrogen bond...
