Congratulations to Sam Bradberry, who today successfully defended his PhD thesis, entitled Design and development of novel self-assembled luminescent lanthanide complexes in solution and in responsive soft materials.
The four year research project was carried out in collaboration with Dr Amir Khan of the School of Biochemistry and Immunology, TCD and Prof. Colin McCoy of Queens University Belfast. Sam’s work has been published in several journals including Chemical Communications and Faraday Discussions. After the viva, Sam joined the rest of the TG group for a celebratory reception in the Trinity Biomedical Sciences Institute.
Dr Oxana Kotova attended the 12th International Symposium on Macrocyclic and Supramolecular Chemistry in conjunction with ISACS: Challenges in Organic Materials & Supramolecular Chemistry, which was held this year in Cambridge Corn Exchange & Guildhall. There she presented a poster entitled “Discrete white-light-emitting Ln-based heterometallic assemblies in solution”. This work was recently published in Chemical Science. The conference included talks from various internationally renowned researchers including Nobel Laureate Prof. Fraser Stoddart, Prof. François Diederich, Prof. Harry Anderson, Prof. David Leigh and Prof. Vivian W.W. Yam amongst many other excellent chemists. Thanks to the organising committee for the excellent meeting.

We would like to welcome two new students, Tony Duggan and Céline Ruijs, to the Gunnlaugsson group. Tony is a 3rd
year Pharmaceutical Healthcare
student from DIT on placement in the group from January until May. Céline is a 4th
year Chemistry student from Université Catholique de Louvain
and will be doing an internship until May. Both of them are working on self-assembly projects with Oxana
Many congratulations to Chris, Dawn and Salvador who had their paper “Structure direction, solvent effects and anion influences in halogen-bonded adducts of 2,6-bis(iodoethynyl)pyridine” accepted in the ACS journal Crystal Growth & Design and to Esther and Steve who had their paper “Cyclen lanthanide-based micellar structures for application as luminescent [Eu(III)] and magnetic [Gd(III)] resonance imaging (MRI) contrast agents” accepted in the RSC journal Chemical Communications. Both papers represent new areas within the TG research group; the former being the first publication from the group on the use of halogen bonding in self-assembly formation, while the latter presents the first examples of the formation of lanthanide based self-assembly micelles. This contribution was also the 200th to be accepted from the TG group. Well done to you all!
Eoin McCarney, 2nd year PhD research chemist in the Gunnlaugsson group, had his first journal article published in Chemical Communications earlier this month. The work reported entails the formation and characterisation of a healable lanthanide luminescent metallogel from 2,6-bis(1,2,3-triazol-4-yl)pyridine (btp) ligands. Co-authors include Gunnlaugsson group member Dr. Joe Byrne who supervised the initial stages of the project, crystallographers Dr. Brendan Twamley and Dr. Miguel Martínez-Calvo, physicists Gavin Ryan and Prof. Matthias Möbius for the rheological studies of the soft matter gel and Prof. Thorri Gunnlaugsson.

An article from the TG Group entitled “The application of chiroptical spectroscopy (circular dichroism) in quantifying binding events in lanthanide directed synthesis of chiral luminescent self-assembly structures” was among the top 25 most downloaded Chemical Science articles from the last quarter of 2014. The article discusses the use of CD and other spectroscopic techniques to probe lanthanide-directed self-assembly behaviour in solution of chiral luminescent systems – a new approach to understanding the behaviour of these systems.
Dr Oxana Kotova, Dr Salvador Blasco, Dr Jon Kitchen and Dr Miguel Martínez-Calvo from the Gunnlaugsson Group worked in collaboration with Dr John O’Brien and Dr Brendan Twamley from Trinity College Dublin and Dr Robert Peacock in Glasgow on this exciting research.
