Ligated Transition Metal Clusters in Solid-state Chemistry
Author: Jean-François Halet
Publisher: Springer Nature
ISBN: 3030251241
Category : Science
Languages : en
Pages : 201
Book Description
This volume dedicated to the memory of Marcel Sergent who was a leader in this field for many years, addresses past achievements and recent developments in this vibrant area of research. Large classes of ligated transition metal clusters are produced either exclusively or most reliably by means of high-temperature solid-state reactions. Among them, the Chevrel-Sergent phases and related materials have generated enormous interest since their discovery in 1971. Today, these materials and their numerous derivatives still constitute a vivid area of research finding some applications not only in superconductivity, but also in catalysis, optics or thermoelectricity to mention a few.

Synthesis and Characterization of Hexanuclear Rhenium Chalcogenide Clusters Containing Potential Two-Photon Absorbing Ligands and the Synthesis and Characterization of Gold-Substituted Coumarins
Author: James Benjamin Updegraff (III.)
Publisher:
ISBN:
Category : Chemistry, Inorganic
Languages : en
Pages : 182
Book Description
Hexanuclear rhenium clusters of the form Re6(u^3-Q8)(PR3)4X2, (Q = Se, S and X = Br- or I- ), and Re6(u^3-Q8)(PR3)4(PEt3)2, where PR3 = tris(4-(4-tert-butylstyrenyl)phenyl)phosphine (PTbs3) have been synthesized and characterized. PTbs3 was chosen for its potential as a two-photon absorbing ligand. Binding of PTbs3 to the cluster core does not completely quench the luminescence of the cluster core. The requirements for Förster energy transfer (FRET) have also been fulfilled. Accessing to the triplet state emission of the cluster core by exciting the PTbs3 ligand using lower-energy light should be achieved. Coumarins substituted at the 6-, 7-, and 8-positions with (phosphine/carbene)gold(I) fragments have also been synthesized in an effort to probe the luminescent properties brought about by a heavy atom such as gold. Each new substituted-coumarin has been characterized by multi-nuclear NMR, elemental combustion analysis, UV-Vis spectroscopy and emissions spectroscopy. In each case, the addition of the gold(I) fragment resulted in the observance of triplet-state emission at room temperature which was not observed for the free coumarin molecule.
