Reactivity Properties of Mixed- and High-Valent Bis(μ-Hydroxide)-Dinickel Complexes
(2021)Despite their potential role in enzymatic systems, there is a dearth of hydroxide-bridged high-valent oxidants. We recently reported the synthesis and characterization of NiIINiIII(μ-OH)2 (2) and Ni2 III(μ-OH)2 (3) species ... -
Tuning the Photo-electrochemical Performance of RuII-Sensitized Two-Dimensional MoS2
(2020)Covalently tethering photosensitizers to catalytically active 1T-MoS2 surfaces holds great promise for the solar-driven hydrogen evolution reaction (HER). Herein, we report the preparation of two new RuII-complex-functionalized ... -
Rapid Iron(III)¿Fluoride¿Mediated Hydrogen Atom Transfer
(2021)We anticipate high-valent metal-fluoride species will be highly effective hydrogen atom transfer (HAT) oxidants because of the magnitude of the H-F bond (in the product) that drives HAT oxidation. We prepared a dimeric ... -
Block Copolymer Thin Films: Self-Assembly of Large Molecular Weight Systems and the Fabrication of Novel Metal/Metal Oxide Nanomaterials
(Trinity College Dublin. School of Chemistry.

(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2021)Two-dimensional (2D) transition metal dichalcogenides (TMDs) are a fast growing and highly researched area in modern materials science. The numerous potential advances, made possible by their oft-quoted, varied, and ... -
The Optimisation of Silicas: Pre-treatment, Grafting & Potential Devices
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2021)Silica materials especially mesoporous silicas are prime candidates as materials which could help solve many issues currently existing such as rising CO2 levels as capture devices and rising levels of cancer worldwide ... -
Enantioselective Alkylation of 2-Oxindoles Catalyzed by a Bifunctional Phase-Transfer Catalyst: Synthesis of (− )-Debromoflustramine B
(2018)A new bifunctional phase-transfer catalyst that employs hydrogen bonding as a control element was developed to promote efficient enantioselective SN2 reactions for the construction all-carbon quaternary stereocenters in ... -
Synthesis and Characterisation of Transition Metal Dichalcogenides and their Heterostructures
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2021)Since the first isolation of graphene in 2004 the interest in 2D materials has exponentially grown. Two-dimensional layered materials demonstrate profoundly different properties when isolated in their mono- or few layer ... -
Synthetic Approaches towards Photoactive Metal-Organic Frameworks
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2021)Metal-organic frameworks (MOFs) are a class of hybrid inorganic-organic materials. They are composed of metal-containing units linked by organic linkers through strong bonds, forming high dimensional frameworks. ... -
Direct laser writing of vapour-responsive photonic arrays
(2021)Using direct laser writing, arrays of optically responsive ionogel structures were fabricated. To demonstrate their responsive nature, visible colour changes in the presence of different solvent vapours were investigated. ... -
