Perspective: Suning Wang on triarylboron compounds for optoelectronics

Suning Wang from Queen’s University, Canada, looks at how electron accepting triarylboranes can be used in optoelectronic applications in this Dalton Transactions Perspective article.

Wang and her PhD student, Zachary Hudson, discuss the role of boron, and the photophysical properties of metal-containing triarylboranes. They go on to review the recent research, looking at triarylboron-containing complexes in OLEDs and as anion sensors, as well their use in MOFs, zinc sensors and as vapochromic materials to detect VOCs.

Unusual structure is ‘silver’ lining in Ag study

A team of scientists from Poland have been playing around with silver-pyrazine complexes and made an unusual crystal structure of a Ag(I) by–product in the process. Piotr J. Leszczyński, Wojciech Grochala and colleagues from Warsaw studied the decomposition of di(pyrazine)silver(II) peroxydisulfate under various heat and chemical processes.

Much work has been carried out on the copper analogue before this but only now is the silver version really being looked at. Read more in this recent Hot Article – FREE to read until the end of October:

HOT Article: Accidentally on purpose, a relatively simple model to study magneto-structural relationships in complex Mn clusters

In this HOT Article, the serendipitous self-assembly of the complex [MnIII2ZnII2(Ph-sao)2(Ph-saoH)4(hmp)2], whose magnetic core consists solely of two symmetry equivalent Mn(III) ions linked by two symmetry equivalent –N–O– moieties, provided Brechin and co-workers with a relatively simple model complex with which to study the magneto-structural relationships in more complicated polynuclear oxime-bridged Mn(III) cluster compounds.

HOT Article: Coordination scales

In this HOT article, Díaz-Torres and Alvarez have developed a scale which attempts to quantify the weakly coordinating character of a variety of solvents and anions towards a transition metal or a lanthanide.  This was made possible by analyzing crystal structures for the presence of coordinated and uncoordinated groups (solvents or anions) in the presence of a transition metal or a lanthanide and extracting from this coordinating ability indices. These indices should prove very useful in providing general trends  allowing comparison between different solvents or anions and should be very useful for the broad organometallic community.

HOT Article: 1-borabenzonitrile

In this HOT article, Cade and Hill describe the synthesis of a salt of the 1-borabenzonitrile anion as its tetrabutylammonium salt and a preliminary exploration of its coordination chemistry in which it behaves as neither a conventional nitrile nor an isonitrile. The authors present computational, spectroscopic and crystallographic evidence for the heterocycle and a ruthenium complex containing the anion as an “arene” ligand.

Hot Article: Understanding [4C+3C] cycloaddition

A group of Spanish scientists have investigated the intramolecular [4C+3C] cycloaddition reaction of allenedienes in this Dalton Transactions Hot article.

The researchers from Universidad de Santiago de Compostela and CSIC used density functional theory to look at the mechanism of the reaction when catalysed by PtCl2 and Au(I). They had a range of questions they wanted to answer, including ‘do the allene substituents affect the reaction mechanism? Are the PtCl2 and Au(I)-catalyzed processes exhibiting a similar profile? Why do some substrate/catalyst combinations give rise to [4 + 2] instead of [4 + 3] cycloadducts?’

Read the full article for FREE to find out what they discovered…
