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 Paper published in Dalton Transactions

Graphical Abstract

Structure of the tetrameric [Zn4(L)4]8+ cation investigated in the work.

Congratulations to Dawn, Chris, Bjørn and Joe for their recent paper in Dalton Transactions titled “A folded [2 × 2] metallo-supramolecular grid from a bis-tridentate (1,2,3-triazol-4-yl)-picolinamide (tzpa) ligand“. In this work, a new flexible bis-tridentate donor ligand containing 1,2,3-triazolyl-picolinamide (tzpa) binding sites was developed, which contained structural elements from two of the group favorites 2,6-dipicolinamide (dpa) and 2,6-bis-(1,2,3-triazolyl)pyridine (btp). The new ligand was then used in the formation of a tetranuclear grid with Zn(II) or Fe(II) ions, which was probed with X-ray diffraction, NMR, UV-Visible spectroscopy and mass spectrometry. It also involved a productive collaboration with Dr Manuel Reuther and Dr John O’Brien from the NMR Spectroscopy Facility in TCD, who provided help in understanding the solution behavior of the material using the T1 spin-lattice relaxation parameter in 1H NMR spectroscopy.
