Anna Aletti, Samuel Bradberry and Dr. Oxana Kotova of the TG group attended Southampton Supramolecular Chemistry Symposium on the 24th of June 2016.
All of them presented posters and, in addition, Samuel gave an excellent talk on “Lanthanide Luminescent Logic – functional organic scaffolds and soft polymers gels as logic gate mimics”.
Our former group member Dr. Joseph Byrne who is currently a postdoctoral researcher in the University of Bern attended the conference as well and presented a poster on his recent work published in Angew. Chem. Int. Ed. on self-templated btp Catenane.
The meeting included speakers and posters from UK Universities and beyond, including an outstanding lecture from the plenary speaker Professor A. P. de Silva.
Abstract: We report the remarkable ability of 2,6-bis(1,2,3-triazol-4-yl)pyridine (btp) compounds with appended olefin amide arms (2) to self-template the formation of interlocked catenane structures (3) in yields of up to 50% when subjected to olefin ring-closing metathesis in CH2Cl2. X-ray diffraction crystallography allowed structural characterisation of both the catenane 3a and the non-interlocked macrocycle 4a. These catenanes show selective triazolyl hydrogen bonding interactions with the tetrahedral phosphate anion when screened against a range of ions; 3a and b being the first examples of selective catenane hosts for phosphate.
Recent statistics show that research from the Gunnlaugsson Group published in RSC journals is gaining attention as Prof Gunnlaugsson is in the top 10% of cited authors in the General Chemistry portfolio of these journals. The highlights of recent attention-gaining articles included “Self-assembly formation of mechanically interlocked - and  catenanes using lanthanide ion [Eu(III)] templation and ring closing metathesis reactions” by Dr Christophe Lincheneau et al. in Chemical Communications, which has been cited 18 times since 2014 and downloaded 1167 times. Also listed was the comprehensive review article of the supramolecular and coordination chemistry of 2,6-bis(1,2,3-triazol-4-yl)pyridine (btp) ligands by Dr Joseph Byrne et al. published in Chemical Society Reviews, which has been cited 18 times since publication and downloaded 1237 times, according to the RSC’s download records up to February 2016.
This month, Dr Joseph Byrne travelled to Hong Kong University in order to work in the laboratory of Prof Vivian Wing-Wah Yam and establish a collaboration, investigating luminescent inorganic complexes and bringing together expertise from the Yam group and the TG Group.
This exchange was made possible through the support of Science Foundation Ireland’s International Strategic Collaboration Programme for China.
Dr Byrne worked closely with postdoctoral fellow Dr Sammual Yu Lut Leung while hosted at HKU.
On Friday 11 December, he gave a seminar to members of the Department of Chemistry about research from the TG Group and had fruitful discussions about these topics.
We were delighted to host secondary student Niamh Murphy from Mercy College for a week in the TG laboratory. Niamh is very interested in pursuing a career in scientific research and so, as part of her Leaving Certificate Vocational Programme course, she got in touch with us about getting some work experience in a working research lab.
Niamh worked with Dr Joe Byrne, helping with the synthesis of a number of ligands for ongoing research and made a valuable contribution to the lab while there.
The TG Group often hosts students for work experience in order to open up the possibility of research to the wider community.
As part of the 20th Annual Science Week, SCI’s All-Ireland group hosted a table quiz in Doyles bar. The quiz was sponsored by Henkel, RSC and ICI.
Against stiff competition from other chemists from Trinity, UCD and various industrial chemists, the first prize was won by a team made up of TG Group members Amy Lynes, Dermot Gillen, Joe Byrne, Anna Aletti and Sam Bradberry.
