The immobilisation of chiral organocatalysts on magnetic nanoparticles: the support particle cannot always be considered inert.
(2011)A systematic study concerning the immobilisation onto magnetic nanoparticles of three useful classes of chiral organocatalyst which rely on a confluence of weak, easily perturbed van der Waals and hydrogen bonding interactions ... -
Immunoliposomes.
(2012)Since their discovery by Bangham about 50 years ago, liposomes have become promising tools in drug delivery systems. This has increased the therapeutic index of many drugs, and offers improved drug targeting and ... -
Impact of Substituents and Nonplanarity on Nickel and Copper Porphyrin Electrochemistry: First Observation of a Cu-II/Cu-III Reaction in Nonaqueous Media
(2014)ABSTRACT Electrochemical studies of the oxidation of dodecasubstitued and highly nonplanar nickel porphyrins in a non-coordinating solvent have previously revealed the first NiIII porphyrin dication. Herein, we investigate ... -
Improving antidepressant drugs: update on recently patented compounds
(2009)Background: According to the World Health Organization, depression is a common condition that affects about 121 million people worldwide. Although the pathophysiological origin of this condition is still unknown, most of ... -
Improving stability of organometallic-halide perovskite solar cells using exfoliation two-dimensional molybdenum chalcogenides
(2020)Organometallic-halide perovskite solar cells (PSCs) are emerging as the most promising next generation solar cell devices. However, the stability is still the main bottleneck of their further development. Here, we introduce ... -
In Search of Highly Emissive Fully Organic Compounds for Application in Molecular Electronics
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2022)The contents of this thesis can be summarised with two separate undertakings, with an overall goal to design, synthesise, and study novel organic materials. The first undertaking (Chapter Two) required detailed synthetic ... -
In vitro cytotoxicity of a library of BODIPY-anthracene and -pyrene dyads for application in photodynamic therapy
(2019)The facile synthesis and in vitro activity of a library of heavy atom-free BODIPY-anthracene, -pyrene dyads (BAD-13–BPyrD-19) and a control (BODIPY 20) are reported. We demonstrate that singlet oxygen produced from dyad ... -
Incremental Introduction of Organocatalytic Activity into Conformationally Engineered Porphyrins
(2019)To study the correlation of macrocycle nonplanarity and catalytic activity of free base porphyrins in detail, a series of six tetraphenylporphyrins with graded degree of β‐ethyl substitution (“H2EtxTPPs” 1–6; x = 0, 2, 4, ... -
Influence of carbon nanostructure and oxygen moieties on dopamine adsorption and charge transfer kinetics at glassy carbon surfaces
(2019)Abnormal levels of the neurotransmitter dopamine have been linked to a variety of neurochemical disorders including depression and Parkinson's disease. Dopamine concentrations are often quantified electrochemically using ... -
Influence of fluoro and cyano substituents in the aromatic and antiaromatic characteristics of cyclooctatetraene
(2015)An exhaustive and systematic study of the structural and electronic properties of cyclooctatetraene (COT) upon substitution of hydrogen atoms by fluoro and cyano groups has been carried out in order to analyse the influence ... -
Influence of meso-linker attachment on the formation of core···π interactions in urea-functionalized porphyrins
(2020)The ability to cover the face of a porphyrin macrocycle selectively is an attractive feature for concepts such as catalysis and anion binding that are reliant on porphyrin core interactions. Herein, we have synthesized ... -
Informational patterns in the genetic code : a chemical and informatics perspective
(Trinity College (Dublin, Ireland). School of Chemistry, 2010)The genetic code has been the subject of extensive investigation for over 50 years. In this research, we have employed various methods to derive empirical determinations of the informational characteristics of this biological ...
