Special Issue Information

Dear Colleagues,

The chemistry of the Sleeping Beauty gold has attracted interest in basic chemistry and applications. Why is gold so attractive? Gold complexes have shown applications in volatile organic compound sensors, liquid crystal displays, optical limiting diodes, surface modification, and rheumatoid arthritis treatment. Gold has served as the main initiative in nanotechnology applications in catalysis, cancer detection, and energy conversion. Aurophilic bonding, which reproduces the attractive forces between the gold atoms, has imparted unique properties in gold chemistry and probably is the foundation of the unique electronic and optoelectronic properties of gold. This Special Issue focuses on recent advances in gold chemistry toward synthesis and applications in the optical, medical, nanotechnological, and catalytic fields.

Submission

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Inorganics is an international peer-reviewed Open Access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. For the first couple of issues the Article Processing Charge (APC) will be waived for well-prepared manuscripts. English correction and/or formatting fees of 250 CHF (Swiss Francs) will be charged in certain cases for those articles accepted for publication that require extensive additional formatting and/or English corrections.

Title: Gold Liquid Crystals in the XXI Century

Abstract
: Since the first gold liquid crystal was described in 1986, much effort has been done to prepare new compounds bearing this property. The review deals with the last results obtained in this new century. Gold(I) has a strong affinity to give linear co-ordination and metal-metal interactions, which produce a rich supramolecular chemistry, and can promote the behavior as liquid crystal. Therefore, most liquid crystals are based on rod-like gold(I) compounds, while gold(III) liquid crystals are scarce. Calamitic and discotic mesogens have been reported, as well as chiral liquid crystals. Weak interactions as H-bonds have also been used to obtain gold mesogens. Some of them exhibit additional properties such as color, luminescence, and chirality. Luminescence has been reported not only in the solid state or in solution, but also in the mesophase. This is relevant for applications in LEDs (Light Emitting Diodes), information storage and sensors.

Title: Reactivity of Mononuclear and Dinuclear Gold(I) Amidinate Complexes with CS2

Abstract: To probe the reactivity of gold-nitrogen bonds, we have examined insertion chemistry with carbon disulfide as well as oxidation with cesium tribromide. The reaction of Ph3PAuCl with Na[(2,6-Me2C6H3N)2C(H)] yields the mononuclear, two-coordinate gold(I) complex, Ph3PAu[κ1-(2,6-Me2C6H3N)2C(H)], 1. The reactivity of 1 with CS2 and CsBr3 produced a mononuclear Au(I) compound, Ph3PAu{κ1-S2C[(2,6-Me2C6H3N)2C(H)]}, 2, and a Au(III) complex, Ph3PAu[κ1-(2,6-Me2C6H3N)2C(H)](Br)2, 3, respectively. We also examined the reactivity of CS2 and CsBr3 with the previously reported dinuclear Au(I) amidinate complex, Au2[(2,6-Me2C6H3N)2C(H)]2, 4. Carbon disulfide insertion with 4 produces a polymeric product, Aun[CS2(2,6-Me2C6H3NC(H)=NC6H3Me2)]n, 5, which shows a dinuclear core with linking aurophilic interactions.  When CsBr3 is reacted with 4 the Au(II,II) product is obtained, Au2[(2,6-Me2C6H3N)2C(H)]2(Br)2, 6.

Title:
PGSE NMR measurements of cationic linear gold(I) complexes

Abstract:
Gold(I) cationic complexes are successfully employed as catalysts in a large variety of organic reactions involving the activation of unsaturated carbon-carbon bonds. A key role in such reactions could be played by the counterion; recent papers show that the anion can influence the yield, the regio- and stereo- selectivity of a catalyst. It was also observed that the anion influences the structure of the catalyst but the detailed explanation of the anion effect is complicated and its role is very difficult to study.  In this contribution, PSGE NMR measurements are conducted on cationic linear gold complexes bearing different L ligands (PR3, NHC, NAC,
alkene, alkyne) in order to study the level of aggregation and the percentage of the ion pairs as a function of concentration, solvent and ligand.
Keywords:
gold, NMR, DFT, PGSE
