The 4-pyridonyl group as a multifunctional electron donor in 1,8-naphthalimide-based photoluminescent and mechanically interlocked coordination compounds
(2018)A new ligand system incorporating the 4-pyridonyl group as a substituent in 1,8-naphthalimide compounds is presented, with the pyridone group acting as both an electron donor for the internal charge transfer (ICT) fluorescence ... -
Supramolecular Chemistry: A Toolkit for Soft Functional Materials and Organic Particles
(2017)Self-assembly has proven to be a powerful tool for the construction of complex superstructures. The assembly of monomers into supramolecular architectures via non-covalent interactions is chiefly directed by the molecular ... -
Luminescent lanthanide (Eu(iii)) cross-linked supramolecular metallo co-polymeric hydrogels: The effect of ligand symmetry
(2019)Two lanthanide luminescent naphthyl-dipicolinic amide (dpa) methacrylate monomers for the synthesis of grafted supramolecular co-polymer gels (hydrogels), and their use as additional crosslinks in robust covalently ... -
Sulfate-Templated 2D Anion-Layered Supramolecular Self-Assemblies
(2019)Using solution and solid-state analyses, we demonstrate that the tripodal N-methylated(1,3,5-benzene-tricarboxamide)-tris(phenylurea) BTA ligands, possessing urea functionalities in the meta position, are able to form ... -
Inosine Can Increase DNA's Susceptibility to Photo-oxidation by a RuII Complex due to Structural Change in the Minor Groove
(2017)Key to the development of DNA-targeting phototherapeutic drugs is determining the interplay between the photoactivity of the drug and its binding preference for a target sequence. For the photo-oxidising lambda-[Ru(TAP)2 ... -

Universal scaling relations for the rational design of molecular water oxidation catalysts with near-zero overpotential
(2019)A major roadblock in realizing large-scale production of hydrogen via electrochemical water splitting is the cost and inefficiency of current catalysts for the oxygen evolution reaction (OER). Computational research has ... -
Investigations into Metal-Binding Groups to Probe the DNA Repair Nuclease SNM1A
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2021)SNM1A is a nuclease that is implicated in DNA interstrand crosslink repair and as such is of importance to regular cellular function. However, little is known about its roles, regulation, interaction partners or posttranslational ... -
