Synthesis of biomedical relevant porphyrins
(Trinity College (Dublin, Ireland). School of Chemistry, 2007)The research carried out in the present study focuses mainly on the synthesis of functionalized, unsymmetrically substituted porphyrins for potential applications in photodynamic therapy. Chapter 1 introduces the different ... -
Investigation and theoretical modeling of the nonlinear optical properties of 5,10-A₂B₂ porphyrins
(Trinity College (Dublin, Ireland). School of Chemistry, 2012)An optical limiter is a device which is transparent to ambient light but becomes opaque upon high intensity laser irradiation. Such irradiation is dangerous to human eyes and light sensitive detectors. Porphyrins, which ... -
The adsorption of amines and other small molecules on platinum surfaces
(Trinity College (Dublin, Ireland). School of Chemistry, 2004)This thesis presents an investigation of the adsorption and thermal decomposition of methylamine, dimethylamine, trimethylamine and s-triazine on Pt(110) and carbon monoxide, nitric oxide and nitrous oxide on Pt(331) using ... -
Development of synthetic strategies towards multiporphyrin arrays
(Trinity College (Dublin, Ireland). School of Chemistry, 2011)The aim of this research was to develop synthetic strategies for the construction of multiporphyrin arrays with enhanced π-conjugation. Porphyrin oligomers with extended conjugation display a bathochromic shift in their ... -
The adsorption of simple amines on platinum surfaces
(Trinity College (Dublin, Ireland). School of Chemistry, 2001)This thesis presents the results of an investigation of the adsorption of methylamine, dimethylamine, trimethylamine and ethylenediamine on Pt(111) and Pt(331). The chemical composition and geometric structure of the clean ... -
Development and investigation of novel transition metal mediated reactions in porphyrin chemistry
(Trinity College (Dublin, Ireland). School of Chemistry, 2009)The aim of this work was to extend the number of existing pathways for the synthesis of porphyrins. The focus was directed towards the development and investigation of new transition metal catalysed reactions in porphyrin ... -
Synthesis, reactivity and modification of novel meso-substituted porphyrins
(Trinity College (Dublin, Ireland). School of Chemistry, 2008)The aim of this work was the synthesis, modification and characterisation of novel meso- substituted porphyrins. In particular, focus was directed towards the development of new synthetic pathways and the improvement of ... -
A computational approach to understanding the deNOₓ properties of Rhodium metal
(Trinity College (Dublin, Ireland). School of Chemistry, 2015)The emission of nitrogen oxides (NOx, x = 1, 2) from combustion engines is a significant contributor to acid rain, smog and the enhanced greenhouse effect. The environmental damage these polluntants have caused, as well ... -
Synthetic studies for photo-triggered release of bioconjugate porphyrin photosensitisers in photodynamic therapy
(Trinity College (Dublin, Ireland). School of Chemistry, 2009)The objective of this research was to synthesise porphyrin linked-bioconjugate photosensitisers that can be released upon irradiation with UV light; aiming to improve photodynamic cancer therapy efficiency. This ... -
The design of biofunctional cinchona alkaloid derived catalysts : a new departure
(Trinity College (Dublin, Ireland). School of Chemistry, 2013)This thesis reports the synthesis of a novel class of quinine derived catalyst and its application to the field of organocatalysis. Initially, a suite of seven novel C-9 phenol and naphthol substituted quinine derivatives ... -
Hybrid organic-inorganic materials : synthesis, solid state characterisation and solution studies of organoarsonate and -phosphonate functionalised coordination clusters and networks
(Trinity College (Dublin, Ireland). School of Chemistry, 2013) -
