New Dalton article on Eu(III) coordination and interlocked molecules

Joe has published a new article in Dalton Transactions about “Europium-directed self-assembly of allyl bis(triazolyl)pyridine (btp) ligands”. The article describes two allyl-appended btp ligands (including a mannose-derivative). Both form luminescent europium(III) complexes with quantum yields 5.4% and 1.9% and with reasonably high stabiltiy constants.

Although in prior work, published during Joe’s time in Thorri Gunnlaugsson’s group, one of these ligands was shown to form self-templated [2]catenanes under ring-closing metathesis conditions, attempts to form Eu(III)-centred catenanes from allyl-appended complexes were not successful due to geometrical and structural constraints. Self-assembly of both ligands with Eu(III) in acetonitrile was studied by UV-Vis absorbance, CD and emission titrations.

Joe Conferences, Presentations, Team

Group members present at conferences around Europe

The Byrne Group have had a busy summer attending various Conferences and Summer Schools.

  • Finn attended the 3rd International Supramolecular Chemistry Summer School in Cagliari, Italy, with a bursary from the LUCES COST Action. He presented a poster titled “Lanthanide Glycoconjugate Complexes as Luminescent sensors for P. aeruginosa”.
  • Sophie presented a poster entitled “Thread-and-Click Assembly of Dual-Active Glycoconjugate [2]Rotaxanes for Selective Lectin Binding” at the International Symposium on Macrocyclic and Supramolecular Chemistry in Bordeaux during the week of the 6th July.
  • Meanwhile, Thomas presented a poster on mechanically interlocked glycoconjugates at the 32nd International Carbohydrate Symposium (ICS) in Bratislava.
  • At the ICS Joe was a proxy national delegate to the International Carbohydrate Organisation Board Meeting and also gave a talk about luminescent lectin-sensing approaches.

The Irish delegates at the ICS are pictured below, including members of the McGarrigle group (UCD) and Paul Murphy’s group (University of Galway).
