Research interest in hydrid inorganic–organic materials is being driven by their application light sources and optical displays. Lanthaniod elements are attractive as light emitters because of the purity of colours that can be produced and also by combining different lanthanoid elements, they can emit white light. However in lanthanoid elements, f–f transitions need to be activated by a bound ligand.

Mark I. Ogden, Massimiliano Massi and their research teams  have found a way of solving the issue of phase segragation in lanthanoid based metallo polymers. When phase separation occurs, the metal complex separates from the organic portion which can affect the emission properties. To overcome this, they copolymerized methyl methacrycalate with a calixarene (basket shaped cyclic oligomer) and then introduced a lanthanoid ion to produce luminescent hybrid materials.

The materials can be changed by loading different combinations of lanthanoid ions which produces different colour emissions – as well as emitting white light.

The RSC’s Divisions are keen to support their members with their careers and their scientific activities. To this end, we have launched two new grants which allow our members to apply for funding from their Divisions for various purposes.

If you are organising an activity, such as a small “no frills” meeting or a young researcher meeting, and you need funds, the Small Grants for Scientific Activities may be able to help, with grants of up to £2000. Our Divisions have already supported a number of people with their activities, such as Prof. Michael Glazer’s exhibition, entitled “The Two Braggs”, celebrating the centenary of the seminal work on X-ray diffraction by the eponymous father and son team.

In addition, the Small Grants are also available to support early career researchers (more than 5 years post PhD) with travel to conferences they are participating in. For full details, please visit the website at: http://rsc.li/small-grants.

We all know how important it is for young PhD students and post-doctoral researchers to participate in conferences and workshops. So, we’re very pleased to announce our new Travel Grants for PhD Students and Post-doctoral Researchers (within 5 years of completion of PhD). You can apply to your Division for up to £800 for travel to any conference or workshop anywhere in the world that will benefit you or your career. More information can be found at http://rsc.li/ecr-travel.

Both grants are available now. Application is easy; in each case, we ask that you read the terms & conditions and fill out a simple application form.

The spirit of these grants is to provide quick, flexible and transparent sources of funding for our members. You should typically receive a response from your Division within two or three months for the Small Grants and Travel Grants, respectively.

We look forward to receiving your applications.

N-heterocyclic carbenes are neutral σ donors and electron rich, making them attractive for use as ligands in transition metal catalysts. By changing the nature of the azole ring (nitrogen heterocycle containing at least one other atom of S, N or O) and the substituents, the electronic and steric properties can be modified.

X-Ray structure of a 6-membered N-heterocylic carbene complex of palladium

Studies of expanded NHCs containing a 6- or 7-membered ring have only recently started to appear in the literature. This includes that of Nechaev and colleagues who have synthesized a series of new 6- and 7-membered NHC palladium complexes. Kolychev and Nechaev screened the complexes as catalysts for Suzuki-Miyaura cross-coupling of heteroaryl chlorides and bromides. They tested the catalysts using ‘green‘ reaction conditions and showed that reaction products are clean with no homo coupling products formed.

These systems are very attractive – it will be exciting to see how expanded ring NHCs are utilized more in the future…
