New Students Join the Research Group, welcome to Tony and Céline!


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.

Lanthanide Nanoagents Article Published in and Featured on the Front Cover of the New Cell Press Journal Chem

Esther’s work on the front cover of Issue 3 of Chem. Chris and Amy helped to design the cover.

Great news on the publication front as Drs Esther Surender and Steve Comby celebrate their paper titled “Two-Photon Luminescent Bone Imaging Using Europium Nanoagents” being recently published in  Chem, a new and upcoming journal from Cell Press. Not only was their work featured on the front cover of the issue, it was also picked up by several of the national broadcasters for Ireland, being reported in RTE news, the Irish Independent, Irish Examiner and Silicon Republic. Congratulations to Esther and Steve on this great achievement! Thanks to all the authors of the article for their contribution. 

Two publications accepted from the group in Crystal Growth & Design and Chemical Communications

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’s first publication in Chemical Communications

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. DOI: 10.1039/C5CC03139G

Top 25: Article among most downloaded Chemical Science papers

cd-titrations-top25An 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.

Sachi presents at “TCD Metals” Seminar Series

As part of the “TsachiTCD MetalsCD Metals” Seminar Series in Trinity College School of Chemistry, Savyasachi A J presented his PhD work in a talk entitled “Luminescent Microspheres: Self-Assembly Studies of Novel Tripodal Ligands with Europium”. In this presentation, recent developments in the self-assembly of terpyridine-based tripodal molecules with europium ions, as well as the application of these compounds towards the discovery of new materials, were discussed.

Starting with titration  experiments of these ligands with Eu(III), the formation of self-assembled structures and coordination polymers from the same ligands at different concentrations was shown by various spectrophotometric techniques. Then the presentation moved towards the development of soft materials like gels from the same ligands. Additionally, the surprising discovery of the formation of spherical microparticles were shown. Later, the discussion advanced towards the experiments performed on the microspheres in order to understand the mechanism of formation, applications and the materials properties of these structures. Throughout the presentation a wide variety of spectroscopic and electron microscopic techniques were discussed and utilised in the exploration of this new class of materials.
