A simple and efficient method using reduced amounts of solvents for the determination polycyclic aromatic sulfur heterocycles (PASHs) in aqueous matrices from a lagoon leachate solid waste petrochemical industry is proposed. The target analytes were previously concentrated disposable pipette extraction (DPX) technique applying gas chromatography-mass spectrometry (GC-MS) analysis. In this innov...

The self-assembly of rigid inorganic cyclophanes comprising cis bridging metal centers connected by aromatic edges has emerged as a promising new area within the realm of hostguest chemistry.1-5 By utilizing the power and simplicity of molecular self-assembly which enables components to arrange themselves into square host cavities, chemists have synthesized a large number of new species with re...

The pH-induced conformational transition in the CuA domain of subunit II of cytochrome oxidase of Paracoccus denitrificans (PdII) has been investigated using various spectroscopic and stopped-flow kinetic methods. UV-visible absorption and circular dichroism studies showed that an increase in pH from 6 to 10 leads to a conformation change with pK(a) = 8.2 associated with the CuA site of the pro...

For the first time oxidative quenching of OsP2N4 chromophores by reactive PtII or PdII sites containing cis, trans, cis-1,2,3,4-tetrakis(diphenylphosphino)cyclobutane (dppcb) is directly observed despite the presence of a saturated cyclobutane backbone "bridge". This dramatic effect is measured as a sudden temperature-dependent onset of a reduction in phosphorescence lifetime in [Os(bpy)2(dppcb...

A kinetically inert, reversible coordination polymer (3) was obtained through complexation of dicyclohexylphosphine telechelic poly(tetrahydrofuran) with palladium(II) dichloride. This coordination polymer is unreactive towards palladium(II) dichloride bis(1-diphenylphosphino)dodecane (4), because ligand dissociation in the coordination polymer is slow. However, upon ultrasonication of solution...
