Call for papers: Themed issues

Dalton Transactions coverWe are delighted to announce four new Dalton Transactions themed issues:

Metallodrugs: Activation, Targeting and Delivery
Deadline: 12th April 2016
Guest Editors: Professor Dr Nils Metzler-Nolte (Ruhr-Universität Bochum), Professor Dr Zijian Guo (Nanjing University)

In 1965, a seminal paper by Barnett Rosenberg appeared in Nature, describing the anti-proliferative properties of a very simple inorganic compound, now known to all of us as Cisplatin. This discovery, and the subsequent clinical approval of Cisplatin, has led to thousands of papers, and it has arguably initiated the field of medicinal inorganic chemistry. Now, 50 years after Rosenberg’s discovery, the field has matured and, beyond Cisplatin, many other compounds have been explored for their anti-proliferative activity. Moreover, chemical creativity has shifted from the mere discovery of new active agents, and elucidation of their mode of action (as difficult as that may be at times) to issues such as delivery of anti-proliferative agents to cancer cells, activation of inorganic prodrugs, and very creative approaches to targeting malignant cells exclusively.

A Themed Issue of Dalton Transactions now seeks to explore these frontiers in the art of medicinal inorganic chemistry. Crucially, the Issue will aim to provide an overview of current progress in three focal points of inorganic drug development: activation (for example, by light, enzymes or external stimuli), targeting (that is, bioconjugates, using the EPR effect, and so on) or selective delivery (to cancer cells or intra-cellularly, by nanoparticles or other carrier systems, and so on).

Although certainly important, the discovery of new compounds or elucidation of a mode of action are not topics for this issue — but Dalton Transactions is of course an excellent place for dissemination of such results in a regular Paper.

Small molecule activation
Deadline: 30th April 2016
Guest Editors: Professor Martin Albrecht (University of Bern), Professor Eric Clot (University of Montpellier), Professor Giulia Licini (University of Padova), Professor Barbara Milani (University of Trieste)

Small molecule activation constitutes one of the main frontiers of inorganic and organometallic chemistry, with much effort directed towards the development of new processes for the selective and sustainable transformation of abundant small molecules such as H2O, NH3, N2, O2, CO, or CO2 into high-value chemical feedstocks and energy resources.

This themed issue will focus on homogenously catalysed activation of small molecules, as well as stoichiometric reactions that further our understanding towards such ends. We invite submissions covering any relevant aspect of small molecule activation including: organometallic chemistry, (electro)catalysis, photochemistry, mechanistic studies, spectroscopy, synthesis, and developments in materials science.

Reactions Facilitated by Ligand Design
Deadline: 10th May 2016
Guest Editor: Professor Jason Love (The University of Edinburgh)

This issue will focus on transformations involving inorganic complexes where a ligand design approach has been used to produce a demonstrable change in reactivity. Papers can be submitted from any area of inorganic or organometallic chemistry, including catalysis, small molecule activation, C–X bond activation, bioinorganic chemistry and supramolecular chemistry. Ligand classes could include pincers, carbenes, macrocyclic ligands, phosphines or metallocenes, with approaches for goal-oriented ligand design involving aspects such as redox non-innocence, steric hindrance, secondary coordination sphere effects and manipulation of Lewis pairs.

Molecular Spintronics: The role of Coordination Chemistry
Deadline: 17th May 2016
Guest Editors: Professor Eugenio Coronado (University of Valencia), Professor Masahiro Yamashita (Tohoku University)

This issue intends to show the impact of coordination chemistry in the emerging field of Molecular Spintronics.

Coordination chemistry provides many examples of molecules that can be useful in this field: from metal complexes that can be incorporated into spintronic devices, as spin collectors or spin filters, to magnetic molecules that can behave as bits of memory or even as spin qubits.

This issue will cover the three different facets of the field, namely: 1) the use of molecules in the development of a new generation of spintronic devices; 2) the miniaturization of the device to reach the single-molecule limit (molecular nanospintronics); and 3) The search for molecular spin qubits of interest in quantum computing.

In this multidisciplinary field, chemists work in close interaction with solid-state physicists, including theoreticians as well as experimentalists, and materials scientists. Contributions coming from the three scientific communities in which these scientists are integrated – Spintronics, Molecular Electronics and Molecular Magnetism – are expected.

Does your research fit into any of these subject areas? If so, we would welcome your contribution. Please see below for further details on how to submit:

How to submit

All types of manuscript – communications, full papers and Perspectives, will be considered for publication. The manuscript should be prepared according to our article guidelines and submitted via our online system.

All manuscripts will be subject to normal peer review and inclusion in the themed issue will be at the discretion of the Guest Editors. Please indicate in your submission which themed issue you would like to be considered for.

Mercury-grabbing ionic liquids hit the gas

Written by Simon Neil for Chemistry World

Scientists in the UK and Malaysia have disclosed the research behind a fast and safe commercial technology for removing mercury from natural gas. The technology is the first solid-supported ionic liquid to be used at an industrial scale, and its development, from laboratory to full plant operation, took just four years.

The mercury-removing ionic liquid system was commercialised for use within the petroleum gas production industry

The mercury-removing ionic liquid system was commercialised for use within the petroleum gas production industry

The vast volume of natural gas that is processed annually by industry contains a pernicious contaminant – hundreds of tons of mercury. This corrosive metal is intrinsically present within hydrocarbon deposits, and it must be removed to mitigate catastrophic damage, not only to the environment but also to the gas-processing plants.

Interested? Read the full story at Chemistry World.

A collection of papers in memory of Lord Jack Lewis

We are very pleased to announce the launch of a commemorative article collection in memory of Lord Jack Lewis.

Lord Jack Lewis, who recently died aged 86, was the 1970 Inorganic Professor at Cambridge for 25 years from 1970 to 1995. Highly energetic and extremely talented, he was among a small band of pioneers who revolutionised inorganic chemistry and must be regarded as one of the true founding fathers of the modern field. As a tribute to Jack, Brian F. G. Johnson, William. P. Griffith, Robin J. H. Clark, John Evans, Brian H. Robinson and Paul R. Raithby have chosen a selection of his papers that they feel demonstrate Jack’s interest and contribution to inorganic chemistry over the course of his career, introducing them in a special Editorial in Dalton Transactions.

We very much hope that you will enjoy this commemorative article collection.

Bridging the gap – small ligands in MOFs

Posted on behalf of Christopher Hinde, web writer for Dalton Transactions

In a recent article from the group of Deanna D’Alessandro at the the University of Sydney, Australia, Liang et al. have shown for the first time a 3D metal-organic framework (MOF) comprised solely of the monocarboxylate ligand derived from formic acid, with exceptionally selective CO2 adsorption properties.

For those involved in MOF chemistry, it is well accepted that in most cases, organic bridging ligands should have at least two coordinating functional groups that link adjacent inorganic secondary building units into a porous crystalline lattice. Therefore, it comes as a complete surprise to find that a porous MOF can be formed entirely of monocarboxylate ligands that are traditionally used to cap and thus prevent further growth of the framework. Through structural characterisation, Liang et al. have shown that the formate takes on two different binding modes within the framework; one that caps the oxyzirconium cluster secondary building units, and another that bridges and interconnects these into a crystalline architecture.

Why is this important, I hear you ask? As the formate ligands are very small, this results in the formation of very small pores that can lead to selectivity in the adsorption of different gases. This is just what has been shown by Liang et al., with adsorption isotherms demonstrating that adsorption of CO2 is a factor of 145 higher than for N2. Potential applications may lead to the sequestration and use of greenhouses gases such as CO2 from the atmosphere.

Hierarchical functionality in MOF structures

Posted on behalf of Christopher Hinde, web writer for Dalton Transactions

Yanfeng Yue and co-workers have developed a novel method for introducing mesoporosity into a series of metal–organic framework (MOF) materials by using “perturbation-assisted nanofusion”, as described in their recent Dalton Transactions paper. The authors exemplified the importance of their work by showing that large dye molecules can be encapsulated in the mesopores for luminescent sensing of volatile organic compounds (see also the image below, from Yue and co-workers).

Encapsulation of large dye molecules in hierarchically superstructured metal-organic frameworks, for ratiometric sensing

Introducing mesoporosity into microporous frameworks has been of interest to materials chemists for several years, in an effort to expand the functionality and widen the potential applications of nanoporous materials.

Microporous materials have proved to be great tools for achieving precision in catalysis, separations and sensing (among others), by using internal surfaces or porosity in a multitude of ways. However, by introducing mesoporosity, one can overcome certain limitations, such as diffusion or small molecule selectivity, and one can even introduce multifunctionality by using the properties of both the micropores and the mesopores within a structure.

Typical procedures for the fabrication of mesopores in MOF structures involve the use of wasteful techniques such as etching or organic templates. However, rather than building mesopores into single crystals of MOFs, Yue and co-workers take a different approach by constructing mesopores from fused MOF nanocrystals that are formed through a highly agitated synthesis procedure (that is, perturbation-assisted nanofusion). The result is the formation of a robust hierarchical superstructure through an inexpensive and economical process.

This out-of-the-box thinking allows the authors to exploit their new ‘bottom-up’ approach to introduce functional mesoporosity into MOF materials, for the sensing of volatile organic compounds.

It is easy to see how this method would be useful to researchers not only in sensing but also in any of the myriad established and emerging MOF applications.

Molecular Memory in a Long-Lasting Mixed Spin State Fe(III) Complex

From early on, we are taught to look at linear mathematical relationships as dependent variables that are determined by the value of an independent variable.

The reason that I find the phenomenon of hysteresis fascinating is that it is the violation of the above concept. By definition, the value of a dependent variable showing hysteresis depends not only on the value of the independent variable but also on whether the independent variable has been increasing or decreasing before it arrives at the value at which a measurement is taken. The dependent variable has a ‘memory’ of its path.

Examples of hysteresis are rare on a molecular level. One of several fascinating aspects of the recent Dalton Transactions paper by Guy Jameson and colleagues is that the (temperature-dependent) magnetism exhibited by the authors’ Fe(III) spin-crossover (SCO) complex shows two hysteresis loops; an example from Jameson and colleagues is shown below.

Magnetic Susceptibility vs Temperature Showing Hysteresis

In transition metal complexes where both high spin and low spin states are possible, SCO occurs when a complex switches from one spin state to the other. Unsurprisingly, this is temperature-dependent, hence the temperature dependence of the magnetism. Hysteresis in magnetic measurements of SCO compounds is known, but Jameson and colleagues report a number of rare properties for the Fe(III) compound that they investigate, [Fe(qsal-Br)2]NO3•2MeOH (where qsal-Br denotes the (N-8-quinolyl)-5-bromo-salicylaldimate ligand).

The vast majority of complexes in which SCO occurs exhibit the phenomenon in a single step — at a certain temperature, all of the molecules in a bulk sample will convert from one spin state to the other. This is only the fifth example of a mononuclear Fe(III) complex that shows full SCO that occurs in two or more discrete increments where symmetry is lost within the molecular structure. In the case of this Fe(III) complex, the temperature range over which some metal nuclei are high spin, and some are low spin (in this case 50% each), is the largest ever reported for a mixed spin-state Fe(III): that is, 96 K.

Here, both steps exhibit hysteresis. The spin-state transitions occur at different temperatures when the authors start with the complex at 300 K and cool it, versus when they warm the complex from 4 K.
