Jamie Humphrey reports from ICBIC 15

This week I attended the 15th International Conference on Bioiogical Inorganic Chemistry (ICBIC)…..

This week I attended the 15th International Conference on Biological Inorganic Chemistry (ICBIC), organised under the auspices of the Society of Biological Inorganic Chemistry.

This was my fourth ICBIC, and as I have been before at previous meetings, I was very impressed with both the quality of the science presented, and the breadth of science covered. There were too many session headings to list here (the full programme can be found on the conference website), but to give an idea of the breadth of biological inorganic chemistry presented, the different sessions covered therapeutics (treatments for malaria, cancer and Alzheimer’s); enzymes (nitrogenase, oxygenase, peroxidase); trafficking (Cu, Ni, Fe); imaging; sensing; bioorganometallic chemistry; and metallomics – with all this great chemistry to cover, the conference spanned 6 days. Sadly, I was only able to attend the first half of the conference.

I knew to expect a warm welcome for delegates at this conference: the biological inorganic chemistry community is very friendly and welcoming. However, we were also blessed to be welcomed by perfect weather in the beautiful city of Vancouver. We could not have wished for a better location for the meeting –  I had heard some very good things about Vancouver, but the reality surpassed the imagination!

With about 700 delegates, ICBIC15 was busy enough to have a buzz about it, but not too busy to feel anonymous (and to ensure everyone could have one of the great cakes served during the morning coffee break – I noticed that I am not the only one with a weakness for cinnamon buns).

The organisers had made a conscious decision to open up the presentations, by having a larger number of contributed talks than there has been in recent ICBICs. This seemed to have worked very well, as it helped to encourage a good number of talks by early career members of the community. While it is always a pleasure to listen to more established chemists, there is something particularly special about hearing from those who are just starting to build their scientific presence and reputation.

The first ICBIC was held 35 years ago, and to celebrate, a number of Jade Anniversary lectures were given by Harry Gray, Ed Solomon, Ken Raymond, Jan Reedijk and David Garner, to name but a few. The Jade speakers had the significant challenge of covering 35 years of chemistry in 20-30 minutes, but they were all up to the challenge!

The organising committee, in particular Chris Orvig, are to be congratulated for selecting an exciting programme of scientific talks and social events for us all  to enjoy, and Sheri and Alison for ensuring all worked well behind the scenes for the week. Everything ran smoothly and seemingly effortlessly, a sure sign of excellent organisation.

You know when you have attended a good conference when you feel reluctant to leave and say goodbye, to the friends who you saw  again and to those you met for the first time. 2013 seems too long to wait for the next ICBIC… ICBIC16 will be held 14-19 July 2013 in Grenoble, France.

Hot Article: Leonard Lindoy’s latest metallosupramolecular research

Read Leonard Lindoy’s latest supramolecular host-guest formation research in this Dalton Transactions Hot article.

Lindoy’s group make helicates and tetrahedral Ni and Fe host complexes from quaterpyridine ligand derivatives, and look how they can control which products they get. They are particularly interested in the cavity volumes of the tetrahedral cages they make, and hope in the future to look at the host-guest chemistry of the cages with the largest cavities.

Getting down to the nitty gritty in layered LiAlO2

Radostina Stoyanova and co-workers have carried out detailed analysis of the zero-field splitting parameters (ZFS) of Mn4+ and Fe3+ ions in LiAlO2 with a layered structure are analyzed both experimentally and theoretically by using high-frequency electron paramagnetic resonance spectroscopy, Neuman superposition model (NSM), DFT and multiconfigurational calculations and reported their work in the recent Dalton Transactions Hot Article.

But why are they doing this analysis you might ask? Well, oxide-based materials, like doped layered LiAlO2, are important components of lithium ion batteries. In order to optimise materials like this for energy storage applications it is necssary to look at their atomic arrangement on a very small scale as Stoyanova and colleagues successfully carry out and report in this paper, which you can read for free until the 5th September.

Local structure of Mn4+ and Fe3+ spin probes in layered LiAlO2 oxide by modelling of zero-field splitting parameters
Radostina Stoyanova, Anne-Laure Barra, Meglena Yoncheva, Elitza Kuzmanova and Ekaterina Zhecheva

Low-cost phosphors for flat panel TVs

Field emission displays (FEDs) have recently gained much attention as they are considered to be the next generation flat panel displays. FEDs have some fascinating features such as great brightness, wide horizontal and vertical view angles, good contrast ratio, high efficiency with a low power consumption and short response times.

Jun Lin and colleagues from Changchun, China are working on possible phosphors for use in FEDs and the group report a promising new Zn2GeO4:Mn2+ submicrorods which might make a useful phosphor in their recent Dalton Transactions Hot Article. The submicrorods were produced using a simple, low cost hydrothermal method without any surfactant assistance. Read the article to find out more – free for you to access until 31 August 2011.

Caroline Knapp wins again at the CCDG 2011 meeting

I am delighted to report that Caroline Knapp was the winner of the Dalton Transactions Poster Prize for the second time at the recent Coordination Chemistry Discussion Group (CCDG) meeting! The annual meeting of the CCDG was held at the University of East Anglia, Norwich, UK from the 7-8 July 2011. Caroline is a member of Jose Goicoechea’s group at the University of Oxford. Congratulations Caroline!

Find out more about Caroline’s research on Zintl ions in her recent Dalton Transactions articles :

A versatile salt-metathesis route to heteroatomic clusters derived from phosphorus and arsenic Zintl anions
Caroline M. Knapp, Joseph S. Large, Nicholas H. Rees and Jose M. Goicoechea
Dalton Trans., 2011, 40, 735-745

Reactivity studies of group 15 Zintl ions towards homoleptic post-transition metal organometallics: a ‘bottom-up’ approach to bimetallic molecular clusters
Caroline Knapp, Binbin Zhou, Mark S. Denning, Nicholas H. Rees and Jose M. Goicoechea
Dalton Trans., 2010, 39, 426-436

The meeting itself was a great success featuring a wide spread in coordination chemistry from actinides to artificial photosynthesis and magnetism to MOFs. The meeting saw excellent talks by keynote speakers, such as Polly Arnold (Edinburgh) and Jean-Francois Carpentier (Rennes), in addition to some great postgraduate presentations. I particularly enjoyed the great conference dinner ‘by the pitch’ at Delia Smith’s restaurant in Norwich City Football Club! Thanks to all those at UEA who organised this year’s exciting CCDG meeting.

Hot Article: Electrochemistry in metal-organic frameworks

In this Dalton Transactions Hot article Andrew Burrows and Frank Marken and colleagues from the University of Bath make MOFs of zincII and aluminiumIII dicarboxylate frameworks with covalently attached ferrocene functional redox groups.

Burrows uses post-synthetic modification to attach the ferrocenyl groups to the frameworks using an amine to amide functional group interconversion. The metal-organic frameworks they made were found to have novel redox active properties, which is an interesting development in the search for designer-electocatalysts.

HOT Article: A step closer to rational design and assembly

This HOT article describes the synthesis and crystal structures of four mono- or bi-cyclic Mo/S/Cu clusters from a pre-designed cluster [(η5-C5Me5)2Mo23-S)4(CuMeCN)2]2+ with tetraphosphine or N,P mixed ligands.  The femtosecond third order non-linear optical (NLO) performances of the products are enhanced due to the increased number of cluster cores.  As both the cluster-based building blocks and the multiple organic linkers are pre-designed, it could be useful for the rational design and assembly of coordination frameworks, possibly allowing the preparation of other new materials with enhanced NLO performance.
