Welcome from the TG Group!

TG_Group-September-2017

[Most of] The TG Group, in the TBSI Boardroom, September 2017.

The TG Supramolecular and Medicinal Chemistry Research Group is based in the School of Chemistry, Trinity College Dublin and is at the cutting edge of research into supramolecular structures, sensor design and materials development. The principal investigator is Professor Thorfinnur Gunnlaugsson.

The TG Group is housed in the Trinity Biomedical Sciences Institute (TBSI), as part of the School of Chemistry. The School is divided between several institutes on and near the main campus, such as the Chemistry Building, the Sami Nasr Institute of Advanced Materials (SNIAM), the Centre for Research on Adaptive Nanostructures and Nanodevices (CRANN) and TBSI (Map).

New paper accepted in Dalton Transactions!

Many congratulations to Trinity College Dublin team Dr. Oxana Kotova, Dr. Steve Comby, Dr. Komala Pandurangan (now at Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR)), Dr. Floriana Stomeo (now at IPSEN Pharma), Dr. John E. O’Brien and Dr. Martin Feeney who in collaboration with Dr. Robert D. Peacock from University of Glasgow and Prof. Colin P. McCoy from Queen’s University Belfast who have had their paper entitled “The effect of the linker size in C2-symmetrical chiral ligands on the self-assembly formation of luminescent triple-stranded di-metallic Eu(III) helicates in solution” accepted in Dalton Transactions.

The article discussed the formation of chiral, luminescent [Eu2:L3] assemblies with high stability constants in solution. However, it was found that the composition of the assemblies in the solid state was more complex. The chirality of the studied systems allowed us to investigate their formation using various techniques including circular dichroism and circularly polarised luminescence spectroscopies and help their development towards materials for the applications in electronics for virtual reality applications (3D screens) and in medical diagnostic.

New additions to the TG group!

TG group welcomes new visiting PhD student Jacobo Gómez González who joined TG group in July and will be working with us until November 2018.

Jacobo is doing his PhD in the University of Santiago de Compostela within the research group of Profs. Eugenio Vazquez and Miguel Vazquez. During his stay in Trinity College Dublin Jacobo will be studying the self-assembly processes between bipyridine based peptide ligands and lanthanide ions in aqueous medium as well as working on the photophysical investigation of tris[2] pseudorotaxane self-assembly with crown ether sliotar conjugate together with Dr. Oxana Kotova and Dr. Samuel Bradberry.

We also welcome Stephen Byrne who joined the TG group as a research scientist in July 2018, having recently completed his degree in chemistry at Trinity College Dublin. He is working on the synthesis of coordination polymers, organic polymers, and DNA intercalators together with Dr. Sankarasekaran Shanmugaraju. Before joining the TG group he worked in labs in Zürich, Kyoto, and Berlin. He will be starting his PhD in The University of Sydney in Prof. Richard J. Payne’s group in January 2019.

Elena attends the International Carbohydrate Symposium in Lisbon

The 29th International Carbohydrate Symposium was held from the 15th to the 19th of July at Faculdade de Ciências, Universidade de Lisboa (FCUL) in Portugal. Representing the TG group, PhD student Elena de Calatrava Perez attended the important event, presenting her poster titled “Glycosidase Activated Release of Fluorescent 1,8-Naphthlimide as Imaging Probes and Drug Delivery Systems” which summarize one of her PhD Projects.

The symposium hosted over a hundred talks regarding all the fields carbohydrates chemistry is involved in and will be back for its 30th edition in 2020 in Shanghai.

Oxana, Sam and Sandra take part in the 27th PhotoIUPAC conference in Dublin

PhotoIUPAC, the biennial global IUPAC conference for photochemistry, came to UCD this July (8th – 13th, 2018) and several TG members contributed throughout the week. Post-doctoral researchers Dr. Oxana Kotova and Dr. Sam Bradberry gave talks titled “Effect of Spacer Size in Chiral Luminescent Di-metallic Eu(III) Helicates” and “Supramolecular Scaffolds for Lanthanide Luminescence”, respectively, describing some of the research they have undertaken recently in the group.

PhD student Sandra Estalayo presented a poster on the Ru(II) complexes for singlet-oxygen generation work that she has been carrying out in her PhD in close collaboration with Prof. John Kelly (TCD). Working backstage, PhD students Jason Delente and Isabel Hegarty volunteered to help run the four parallel sessions throughout the week. The group were exposed to exciting and varied science from all corners of the globe, early career researchers and established names from every field of photochemistry, in what was an excellent and diverse programme of talks.

The conference, at its 27th edition, was organised by Dr. Susan Quinn of UCD and Prof. Miguel A. Garcia-Garibay from UCLA. It showcased world-class research in photochemistry with contributors from over 40 countries and was a very stimulating meeting. The 28th meeting will be held in Amsterdam in 2020. See you there, PhotoIUPAC!

Group Trip for the TG Group

As the sun is blessing Ireland with great days, the TG group decided to have a group trip in the afternoon. After long consultation, the group decided to go for a walk along the coast between Greystones and Bray. The group meet at Greystones, then followed the trail all the way to Bray, where, after ice creams, a short rest on the beach (with some very brave TGs who decided to have a swim) had a toast to celebrate the great day. Until the next time!

Elena presents at the 70th Chemistry Research Colloquium at Queen’s University, Belfast.

On Friday 22nd June, Elena represented the Organic Chemistry Department of TCD at the annual Irish Universities Chemistry Research Colloquium at Queen’s University of Belfast, with a talk on the development of glycosylated naphthalimides as prodrugs for medicinal applications. The Colloquium, in its 70th edition, started on Thursday 21st, and highlighted the outstanding research conducted by the best young chemists at third level institutions across Ireland, involving more than 60 students between posters and oral presentations.
Great Job Elena!

Bruno, Hannah and Isabel present their work at the Third Year Talks in TCD

The annual Third Year Talks took place on Tuesday 29th May, so Bruno, Hannah and Isabel, as third year students had a chance of presenting their work. The event, sponsored by Eli Lilly, involved 38 students from TCD, UCD and DIT who presented their research in the Hamilton Building on the Trinity Campus.

Isabel talked about her btp-based metal ion complexes during the Inorganic Chemistry session; Hannah presented her work with bypiridine derivative complexes of d and f metal ions in the New Ligands session; while Bruno talked about his work on f metal ion complexes as indirect probes of peptidic phosphorylation in the Analysis of Biologic session.

Our congratulations go to all the students who participated, and especially to Bruno, Hannah and Isabel for their great job representing the TG group!
