The nitrogen oxides NO2, NO, and N2O are among the most potent air pollutants of 21st century. A bimetallic RhI–PtII complex containing an especially designed multidentate phosphine olefin ligand is capable catalytically detoxifying these in presence hydrogen to form water dinitrogen as benign products. catalytic reactions were performed at room temperature low pressures (3–4 bar for combined g...

This paper reviews some of the more interesting and recent phenomena associated with the metal ion cage chemistry involving hexaazamacropolycycles. Synthetic aspects are addressed in relation to making cages with smaller and larger hole sizes in order to modulate redox potentials and electron transfer rates. The introduction of substituents is also examined in relation to these factors along wi...

Hydrodynamic size-minimized quantum dots (QDs) have outstanding physicochemical properties for applications in multicolor molecular and cellular imaging at the level of single molecules and nanoparticles. In this study, we have reported the aqueous synthesis of Ag2S QDs by using thiol-based multidentate polymers as capping reagents. By regulating the composition of the precursors (AgNO3 and sul...

A new potentially hexadentate P(2)N(4) ligand has been prepared and its coordination chemistry to Pd(II) and Pt(II) investigated. The ligand bonds in a chelating fashion via the diphosphine backbone to PdCl(2) and PtCl(2) while the appended pyridyl groups remain non-bonding. Abstraction of the chloride ions from the platinum complex results in fluxional exchange of the pyridyl groups in solutio...

Four dinuclear lanthanide complexes [Gd2 (H2L)2 (µ-piv)2 (piv)2]·2CHCl3 (1), [Tb2 (H2L)2 (µ-piv)2 (piv)2]·2CHCl3 (2), [Dy2 (H2L)2 (µ-piv)2 (piv)2]·2CHCl3 (3) and [Eu2 (H2L)2 (µ-piv)2 (piv)2]·2CHCl3 (4) were synthesized by the reaction of appropriate Ln(III) chloride salts and a multidentate ligand, 2,2'-(2-hydroxy-3-methoxy-5-methylbenzylazanediyl)diethanol (H3L) in the presence of pivalic acid...
