Cubane and Triptycene as Scaffolds in the Synthesis of Porphyrin Arrays
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2020)The primary aim of this research was to synthesise multichromophoric arrays that are linked through rigid isolating units with the capacity to arrange the chromophores in a linear and fixed orientation. The electronically ... -
Highly Efficient One-Dimensional Triplet Exciton Transport in a Palladium-Porphyrin-Based Surface-Anchored Metal-Organic Framework
(2019)Efficient photon harvesting materials require easy-to-deposit materials exhibiting good absorption and excited-state transport properties. We demonstrate an organic thin-film material system, a palladium-porphyrin based ... -
Metallo-Supramolecular and Bioinspiried Coordination Compounds for H2O Oxidation
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2020)Ever-increasing energy demands and associated climate change issues impose imperative scientific challenges to society. Switching to an economy based on the carbon-free, high density energy carrier H2 represents a promising ... -
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 ... -
Molecular Engineering of Nonplanar Porphyrin and Carbon Nanotube Assemblies- a Linear and Nonlinear Spectroscopic and Modeling Study
(2011)The importance of molecular conformation to the nature and strength of noncovalent interactions existing between a series of increasingly nonplanar tetraphenylporphyrin (TPP) derivatives and carbon nanotubes was systematically ... -
New Materials for Controlled Singlet Oxygen Generation
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2021)Singlet oxygen is notoriously uncontrollable, suffers from poor selectivity, and has fast decomposition rates in biological media. Across the scientific community, there is an enduring effort to refine singlet oxygen ... -
On the Synthesis and Utilization of geminal-Dimethyl Hydroporphyrins and Tetraphenylethylenes in Photodynamic Therapy
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2022)Chapter 1 introduces the main concepts of this thesis: photodynamic therapy (PDT), chlorins and photosensitizer arrays. In the case of PDT multiple topics are discussed, namely, the qualities of an ideal photosensitizer, ... -
Porphyrins as Colorimetric and Photometric Biosensors in Modern Bioanalytical Systems
(Wiley, 2020)Advances in porphyrin chemistry have provided novel materials and exciting technologies for bioanalysis such as colorimetric sensor array (CSA), photo-electrochemical (PEC) biosensing, and nanocomposites as peroxidase ... -
{rac-5-[Meth-oxy(phen-yl)meth-yl]-10,20-diphenyl-porphyrinato}nickel(II)
(2011)The title compound, [Ni(C40H28N4O)], was obtained from a Grignard reaction of the respective formyl-porphyrin to yield {5-[hy-droxy(phen-yl)meth-yl]-10,20-diphenyl-porphyrinato}nickel(II), followed by crystallization from ... -
Surface-confined formation of conjugated porphyrin-based nanostructures on Ag(111)
(2021)Porphyrin-based oligomers were synthesized from the condensation of adsorbed 4-benzaldehyde-substituted porphyrins through the formation of C[double bond, length as m-dash]C linkages, following a McMurry-type coupling ... -
Thiourea organocatalysts as emerging chiral pollutants: En route to porphyrin-based (chir)optical sensing
(2021)Environmental pollution with chiral organic compounds is an emerging problem requiring innovative sensing methods. Amino-functionalized thioureas, such as 2-(dimethylamino)cyclohexyl-(3,5-bis(trifluoromethyl)phenyl)thiourea ...
