A series of d10 coinage metal thiosalicylate coordination polymers (CPs) is reported. The 1D structures the three CPs are formed by M3S3 fused hexagons for Cu and Ag compounds interpenetrated helical chains Au CP. Depending on metal, solid-state red NIR emissive obtained with quantum yields up to 50 %, providing a great opportunity replace actual critical raw materials.

Flavins are a fundamental class of biomolecules, whose photochemical properties strongly depend on their environment and their redox and metalation state. Infrared multiphoton dissociation (IRMPD) spectra of mass selected isolated metal-lumiflavin ionic complexes (M+LF) are analyzed in the fingerprint range (800-1830 cm-1) to determine the bonding of lumiflavin with alkali (M=Li, Na, K, Cs) and...

silver coins of alexander of macedonia, until the arrival of parthians in the 1st century bc, have been put in wdxrf in order to determin ag, cu, pb and au as major and trace elements for fineness, debasement and refinement of silver in ancient persia. seleucid kingdom from 4th to 1st century bc was succeeded by several dynasties and kings. but the chemical composition of their silver coins an...

Recent work on Ancient Greece sheds light on the origins of money and its effects on economy and society. This review essay analyses such work and relates it to themes familiar to economists. It examines monetary functions in the heroic world and the effects of introducing coinage in Classical Athens. It attends to the role of the state in the development of money and to the form which money to...

N-heterocyclic carbene stabilized phosphinidene IMes·PPh has been used as a bridging ligand to isolate a group of closely related molecules involving all three coinage metal ions. The bis-copper(I) chloride, bis-silver(I) chloride and bis-copper(I) bromide adducts of IMes·PPh crystallize as halide ion bridged octanuclear molecules while the [IMes·PPh](AuCl)2 adduct remains monomeric. These mole...

In 2004 the term “designer baby” made the transition from sci-fi movies and weblogs into the Oxford English Dictionary, where it is defined as “a baby whose genetic makeup has been artificially selected by genetic engineering combined with in vitro fertilization to ensure the presence or absence of particular genes or characteristics.” This coinage was prompted by recent advances in genetics th...

A series of cationic white phosphorus complexes of the coinage metals Au and Cu have been synthesised and characterised both in the solid state and in solution. All complexes feature a P4 unit coordinated through an edge P-P vector (η(2)-like), although the degree of activation (as measured by the coordinated P-P bond length) is greater in the gold species. All of the cations are fluxional on t...

The optical properties of metals arise both from optical excitation of interband transitions and their collective electronic, or plasmon, response. Here, we examine the optical properties of Cu, whose strong interband transitions dominate its optical response in the visible region of the spectrum, in a nanoshell geometry. This nanostructure permits the geometrical tuning of the nanoparticle pla...

Phosphorylated α-hydroxyallenes 1 and 2 were smoothly converted into the corresponding 2,5-dihydrofurans 3 and 4 in an 5-endo-trig cycloisomerization reaction by using 5 mol % of coinage metal salts as catalyst. Experimental conditions such as the type of the solvent, the reaction temperature, the mol % and the type of the catalyst were optimized. This mild and efficient cyclization method can ...
