A Mn13-cluster based coordination polymer as a co-catalyst of CdS for enhanced visible-light driven H2 evolution
(2018)A coordination cluster-based polymer was used for the first time as a noble-metal-free co-catalyst of CdS, giving rise to significantly enhanced photocatalytic H2 production. This work demonstrates the feasibility of cluster ... -
Assembly, disassembly and reassembly: a “top-down” synthetic strategy towards hybrid, mixed-metal {Mo10Co6} POM clusters
(2019)Polyoxometalates (POMs) are commonly prepared using a “bottom-up” synthetic procedure. The alternative “top-down” approach of disassembling a pre-formed POM unit to generate new synthetic intermediates is promising, but ... -
Tuning the Catalytic Water Oxidation Activity through Structural Modifications of High-Nuclearity Mn-oxo Clusters [Mn18M] (M = Sr2+, Mn2+)
(2021)The water oxidation half-reaction is considered the bottleneck in the development of technological advances to replace fossil fuels with sustainable and economically affordable energy sources. In natural photosynthesis, ... -
Pyrrole-based Photosensitisers for Photomedicine. Synthesis, Photophysical and Photobiological Evaluation of Chlorins and Dipyrrin Complexes
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2022)Photodynamic therapy (PDT) is a light activated therapy which involves a drug-photosensitiser (PS), light, and molecular oxygen. First, the PS is administered via a systemic or topical route and then it accumulates in the ... -
Computational Modelling and Design of Cathode Materials for Sustainable Energy Applications
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2022)Unravelling the activity and selectivity of novel heterogeneous catalysts requires a deep understanding of the effects unfolding at the catalytic surface. Particularly, this thesis emphasises the relevance of dopant ... -
Semi-synthetic Approaches to N-Glycosylation: A Story of Thiol-Ene Methodology, and Interferon-γ
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2022)The following thesis, entitled “Semi-synthetic Approaches to N-Glycosylation: A Story of Thiol-Ene Methodology, and Interferon-γ” is composed of six chapters. The first chapter provides an overview of the key concepts ... -
Antimicrobial formulation and functionalization of photosensitizers for antimicrobial photodynamic therapy (aPDT)
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2022)To provide a long-lasting solution to infections affecting the current world scenario, antimicrobial photodynamic therapy (aPDT) offers a non-invasive means to destroy pathogenic microbes via formation of reactive oxygen ... -
Examination of the organocatalysed reactions between azides and cyclic anhydrides
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2022)Azide is encountered in organic synthesis as both a functional group and as and an ion, and provides a valuable means of incorporating nitrogen into target compounds. The intrinsic nucleophilicity of azides can be beneficial, ... -
Methods Development for the Synthesis of Biologically Relevant Porphyrins and Porphyrin Rigid Linker Arrays
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2022)This research focuses on two main aspects: The synthesis of new derivatives of naturally occurring porphyrins and the preparation of non-natural chromophore-rigid linker conjugates as potential bioisosteres and mimics of ... -
Optimization of Zn-Mn ferrite nanoparticles for low frequency hyperthermia: Exploiting the potential of superquadratic field dependence of magnetothermal response
(2022)Magnetothermal applications of nanoparticles in biomedicine are currently limited by low thermal responses to oscillating magnetic fields on one side and by detrimental physiological effects of electromagnetic radiation ... -
Radical-mediated thiol–ene ‘click’ reactions in deep eutectic solvents for bioconjugation
(2022)Herein, we report the first application of deep eutectic solvents (DESs) in radical-mediated hydrothiolation reactions. Under UV and atmospheric-oxygen mediated conditions, the thiol–ene reac tion was applied to amino ... -
