Fabrication and characterisation of micro- and nano- structures with high aspect ratio
(Trinity College (Dublin, Ireland). School of Chemistry, 2011)The main aim of the work presented in this thesis was to develop novel high aspect ratio micro- and nano- structures by using metal alkoxide derived sol-gels and polymer solutions and infiltrating them into porous templates. ... -
Fabrication and characterisation of photonic nanowires
(SPIE, 2008)In recent years the application of nano-porous templates, such as anodic alumina and PTFE, in the production of cylindrical nanostructures has been vast. In our work we used porous alumina membranes to produce luminescent ... -
Fabrication of Nanoporous Membrane-like Thin Layers via Block Copolymer Lithography of P2VP-b-PS Inverse Systems and their Potential Applications
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2024)The large-scale fabrication of nanoporous materials and substrates has generated significant research interest on account of the wide range of possible applications, including nanophotonics, optoelectronics, biomedical ... -
A facile "bottom-up" approach to prepare free-standing nano-films based on manganese coordination clusters.
(2013)We present herein a novel method to prepare free-standing Dried Foam Films (DFFs) whereby individual polynuclear manganese complexes cover quantitatively the holes of micro-grids; the fabricated, homogeneous films have a ... -
Fast Hydrocarbon Oxidation by a High¿Valent Nickel¿Fluoride Complex
(2020)In the search for highly reactive oxidants we have identified high‐valent metal–fluorides as a potential potent oxidant. The high‐valent Ni–F complex [NiIII(F)(L)] (2, L=N,N′‐(2,6‐dimethylphenyl)‐2,6‐pyridinedicarboxamidate) ... -
Fast quantification of water in single living cells by near-infrared microscopy
(Royal Society of Chemistry, 2004)We have set up a near-infrared microscope using a tuneable diode laser in the range from 1530 to 1570 nm. This spectral range is close to the peak of the water overtone absorption. We used this new microscope to study ... -
Fe(III)-doped coordination polymer of Mn13-clusters with improved activity for oxygen reduction reaction
(2019)Fe(III) dopants have been introduced into a porous coordination polymer of Mn13-clusters to form composite materials. The resulting Fe@Mn13-polymer showed enhanced oxygen reduction reaction (ORR) activity, making it a ... -
Ferrocene containing polyaromatic hydrocarbons and the formation of a discotic nitrogen-heterosuperbenzene
(Trinity College (Dublin, Ireland). School of Chemistry, 2009)Chapter 1 describes the synthesis and characterisation of a series of novel ferrocene containing polyphenylene compounds. These consist of polyphenylene molecules containing one, two, four and six ferrocene moieties. Also ... -
Ferrocenylalkynes as ligands in transition metal complexes
(2001)Several ferrocenylalkynes have been prepared and their reaction with dicobalt octacarbonyl led to the formation of [Co2(CO)6(?-?2 ? ?2-ethynylferrocene)] 1, [Co2(CO)6(?-?2 ? ?2-1,4-bis(ferrocenyl)butadiyne)] 2, [(Co2(CO)6)2(?-?2 ... -
Few-Layer MoS2/a-Si:H Heterojunction Pin-Photodiodes for Extended Infrared Detection
(2019)Few-layer molybdenum disulfide (FL-MoS2) films have been integrated into amorphous silicon (a-Si:H) pin-photodetectors. To achieve this, vertical a-Si:H photodiodes were grown by plasma-enhanced chemical vapor deposition ... -
Fiat Lux : the synthesis and manipulation of molecular scaffolds for photodynamic therapy and light-harvesting arrays
(Trinity College (Dublin, Ireland). School of Chemistry, 2014)Molecular scaffolds are an emerging paradigm that offers chemists the use of preformed chemical structures that can be manipulated structurally and synthetically for use in a plethora of applications. The goal of the ... -
Flexibility in Coordination Polymers: Structure, Topology, Porosity, and Addressability
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2019)Metal-Organic Frameworks (MOFs) are a research area approaching maturity and the industrial application of MOFs to a number of pressing challenges is imminent. These materials are exciting for their porosity and chemical ... -
Flexible Metal−Organic Frameworks for Light-Switchable CO2 Sorption Using an Auxiliary Ligand Strategy
(2019)We report the synthesis and characterization of two photoactive metal–organic frameworks (MOFs), TCM-14 and TCM-15. The compounds were synthesized by incorporating 4,4′-azopyridine auxiliary ligands into pto-type scaffolds ... -
