New work on the luminescent sensing of organic solvents accepted

Many congratulations to Sachi, Bruno and David, who have had their paper on the generation of highly luminescent functional solid-state material, “Self-assembled bright luminescent hierarchical materials from a tripodal benzoate antenna and heptadentate Eu(III) and Tb(III) cyclen complexes” accepted in Frontiers of Chemical Science and Engineering (Front. Chem. Sci. Eng. 2019, DOI:10.1007/s11705-018-1762-3). This work, achieved in collaboration with the Prof. Wolfgang Schmitt research group here at TCD covers the use of self-assembly between cyclen-based lanthanide (Europium and Terbium) complexes and a tripodal ligand which yields a luminescent amorphous material (red and green respectively, as shown below) that can be used for the sensing of solvents such as MeOH, CH3CN and THF.

Sam Bradberry successfully defends his PhD thesis

IMAG3236Congratulations 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.

 

Oxana presents at ISMSC 2017 in Cambridge

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.

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
