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.

New Dalton Frontier Article on lanthanide luminescent soft-material published

Many congratulations to Oxana, Sam and Sachi, who had their invited Frontier article accepted in Dalton Transaction, “Recent advances in the development of luminescent lanthanide-based supramolecular polymers and soft materials” (Dalton Trans., 2018, 47, 16377-16387. DOI:10.1039/C8DT03768J). This work reviews some of the most recent use of luminescent lanthanides ions as crosslinking moieties to generate functional soft materials, giving the readership of Dalton a fantastic inside into this fast-growing area of material research.

Oxana, Sam Sachi

New paper accepted in Chem. Commun.

Many congratulations to Dr. Sankarasekaran Shanmugaraju (Raju), Dr. Bjørn la Cour Poulsen (former PhD student), Dr. Aramballi J. Savyasachi, Hannah L. Dalton and Dr. Chris Hawes (now at Keele University, UK) who have in collaboration with Prof. Graeme Watson and Dr. D. Umadevi (School of Chemistry, TCD) have had their paper entitled: “Synthesis, structural characterisation and antiproliferative activity of a new fluorescent 4-amino-1,8-naphthalimide Tröger’s base-Ru(II)-curcumin organometallic conjugate” accepted for publication in Chem. Commun.

In this communication, they have reported the synthesis, photophysics and biological investigation of fluorescent 4‐amino‐1,8‐naphthalimide Tröger’s bases and a new Tröger’s base p‐cymene‐Ru(II)‐curcumin organometallic  conjugate;  these  compounds  showed  fast  cellular  uptake  and  displayed  good  luminescence  and  cytotoxic against cervical cancer cells.

The journal Chem. Commun. is published by the RSC and the paper is now available online for early view: 10.1039/C8CC01584H

Sachi successfully defends his PhD thesis!

Congratulations to Sachi, who successfully defended his PhD thesis today, entitled “Luminescent Self-assembled Supramolecular Polymers and Microspheres Based on Benzene-1,3,5-tricarboxamide (BTA) Derivatives”.

After the viva examination, Sachi and his examiner David K. Smith joined the rest of the TG group for a celebratory reception in the Trinity Biomedical Sciences Institute.

Isabel wins a poster prize at Supramolecular Chemistry Ireland 2017 at Maynooth

The Gunnlaugsson Group attended the Supramolecular Chemistry Ireland (SCI 2017) conference in Maynooth University yesterday. The conference, organised by former group member Dr Rob Elmes, brought together an array of international speakers for a jam-packed day of lectures and short talks.

Several members of the group presented their work at the poster session, with second year PhD student Hannah Dalton giving a flash talk on “Metallosupramolecular assemblies of a family of N,N,Oterdentate ligands”, work which was recently published in Crystal Growth and Design.

Many congratulations to Isabel Hegarty, who beat a tough field to win the prize for best poster, for her poster entitled “Lanthanide Directed Self-Assembly of a Series of btp Derivatives”

TG Group bid farewell to summer project undergraduate student Aisling Ryan

Aisling completed her two month summer project within the Gunnlaugsson group which she started on 6th of June and finished on 29th of July 2016. She has been an excellent addition to the group and has been working on the synthesis of tripodal terpyridine-based ligands for the formation of supramolecular polymers and gels with Sachi and Oxana. We wish her the very best of luck in her future studies and endeavors!

Strong showing from TG Group at 68th Chemistry Colloquium in Cork

Nine members of the TG Group left the Pale behind and travelled to University College Cork on the 23rd & 24th of June for the 68th Universities Chemistry Colloquium. Both Savyasachi AJ and Eoin McCarney gave 25 minute oral presentations on their work on the Thursday and Friday morning sessions respectively.

Meanwhile Bjørn la Cour Poulsen and Amy Lynes presented their posters at the designated poster session. Dermot Gillen, Sandra Estalayo Adrian, Bruno D’Agostino, Hannah Dalton and Isabel Hegarty all attended and gained a great taste of the flavour of the chemical research being conducted from all disciplines from all over the country.

TG Group and fellow Trinity delegates at the Colloquium BBQ

 

On the Thursday evening all delegates attended the traditional Colloquium BBQ where research chemists were suitably nourished, collaborations were strengthened and friends were made.

The TG Group would like to thank UCC for their hosting of the event and their accommodation of the TG Group members during their stay.
