N-[4-(Di-2-pyrrolylmethyl)phenyl]acetamide
(2007)The crystal structure of the title compound, C17H17N3O, shows the formation of infinite chains of molecules that are linked via hydrogen bonds involving the acetamide group. The carbonyl O atom forms hydrogen bonds with ... -
The N-carbamoyl squaramide dimer: A compact, strongly associated H- bonding motif
(1999)N-Carbamoyl squaramides 3, readily available from dialkyl squarate 5, form hydrogen-bonded dimers in solution and in non-polar organic solvents; in CDCl3 they show no significant dissociation down to concentrations of ?0.5 mM. -
N-containing polyaryl ligands in coordination and supramolecular chemistry
(Trinity College (Dublin, Ireland). School of Chemistry, 2007)Part 1 describes the synthetic route and the characterisation of a family of nitrogen heterosuperbenzene compounds. Those polyaromatic ligands, which contain a fused dipyrimidine unit possess unusual photophysical properties ... -
N-Heterocyclic carbene-catalysed transformations : the crossed benzoin condensation and oxidative aldehyde esterifications
(Trinity College (Dublin, Ireland). School of Chemistry, 2016)The focus of this thesis is the development of a suite of heteroazolium ion-based salts as precursors to N-heterocyclic carbene (NHC) catalysts for a range of transformations involving aldehyde substrates. It has been ... -
N-Heterocyclic carbene-mediated reactions : controlling the fate of the Breslow Intermediate
(Trinity College (Dublin, Ireland). School of Chemistry, 2015)We have developed a highly efficient, broad scope, additive-free mild protocol for the oxidative carbene-catalysed esterification of aldehydes. We have unambiguously identified benzoin as the oxidised species in these ... -
N-substituted Pyridazines as Building Blocks in Novel Supramolecular Architectures
(2009)A series of mono, 1,4-di and 1,3,5-tri 4-substituted 3,6-di(2-pyridyl)pyridazines were analyzed to evaluate the substituent and steric effects in the crystal packing. -
NanoElectrochemical studies of 2D Materials for Energy Storage and Conversion using Scanning Electrochemical Cell Microscopy
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2023)Electrochemical systems are of critical importance in modern society as they enable the conversion of electricity from renewable sources into chemicals and materials. The integration of nanomaterials in energy storage and ... -
Nanoelectromechanical relays for low power integrated circuits
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2019)The semiconductor industry roadmap was described by Intel cofounder, Gordon Moore, fifty years ago when he predicted that the number of transistor devices on a silicon integrated circuit would double with every new generation ... -
Nanoelectromechanical sensors based on suspended 2D materials
(2020)The unique properties and atomic thickness of two-dimensional (2D) materials enable smaller and better nanoelectromechanical sensors with novel functionalities. During the last decade, many studies have successfully shown ... -
Nanometer-size metal complexes : magnetic materials and DNA probes
(Trinity College (Dublin, Ireland). School of Chemistry, 2004)The work described in this thesis was carried out as part of the European TMR Network “Nanometer-size metal complexes” (Contract N ERBMRXCT980226). The synthesis of Cr(III) homoleptic and heteroleptic polypyridyl complexes ... -
