Novel Technique for Developing E-Textiles: Printing MXene Supercapacitors on Fabrics for Wearable Electronics
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2025)The increasing demand for miniaturised and flexible wearable electronics is driving the rapid growth of electronic textiles (e-textiles). In this context, microsupercapacitors (MSCs) are becoming essential as energy storage ... -
High-Valent Cobalt-Difluoride in Oxidative Fluorination of Saturated Hydrocarbons
(2025)The heme paradigm where Fe=O acts as the C−H oxidant and Fe−OH rebounds with the formed carbon-centered radical guides the design of the prototypical synthetic hydroxylation catalyst. We are exploring methods to evolve ... -
Reduction of Exfoliated MoS2 Nanosheets Yields the Semi-Conducting 2H-polymorph Rather Than the Metallic 1T-polymorph
(2024)Delaminated two‐dimensional (2D) transition metal dichalchogenides (TMDs) have attracted significant attention due to their potential application in electronics, catalysis, and biomedical devices. Chemical derivation of ... -
Preparation and characterization of MnIIMnIII complexes with relevance to class Ib ribonucleotide reductases

A CoII-Hydroxide Complex That Converts Directly to a CoII-Acetamide during Catalytic Nitrile Hydration
(2024)In exploring structural and functional mimics ofnitrile hydratases, we report the synthesis of the pseudo-trigonalbipyramidal CoII complexes (K)[CoII(DMF)(LPh)] (1(DMF)),(NMe4)2[CoII(OAc)(LPh)] (1(OAc)), and (NMe4)2[CoII ... -
Class Ib Ribonucleotide Reductases: Activation of a Peroxido-MnIIMnIII to Generate a Reactive Oxo-MnIIIMnIV Oxidant
(2024)In the postulated catalytic cycle of class Ib Mn2 ribonucleotide reductases (RNRs), a MnII2 core is suggested to react with superoxide (O2·-) to generate peroxido-MnIIMnIII and oxo-MnIIIMnIV entities prior to proton-coupled ... -
Synthesis, Characterisation, and Functionalisation of Charged Two-Dimensional MoS2
(2023)The applications of exfoliated MoS2 are limited by its inert surface and poor interface. We have activated the surface of exfoliated 2H-MoS2 by reacting it with NaBH4, forming an n-doped material as demonstrated by a ... -
Hydrocarbon Oxidation by a Porphyrin-π-Cation Radical Complex
(2023)Heme and chlorin π-cation radical oxidants are widely implicated in biological and synthetic oxidation catalysis. Little insight into the role of π-cation radicals in proton coupled electron transfer (PCET) oxidation is ... -
Platinum(II) complexes of aryl guanidine-like derivatives as potential anticancer agents: between coordination and cyclometallation
(2025)The preparation of a wide variety of Pt(II) complexes with aryl guanidines and their potential application as anticancer agents have been explored. A relatively facile synthesis of cyclometallated Pt(II) complexes of ... -
Synthesis and Characterization of a Masked Terminal Nickel-Oxide Complex
(2023)In exploring terminal nickel-oxo complexes, postulated to be the active oxidant in natural and non-natural oxidation reactions, we report the synthesis of the pseudo-trigonal bipyramidal NiII complexes (K)[NiII(LPh)(DMF)] ... -
Evidence for a High-Valent Iron-Fluoride That Mediates Oxidative C(sp3)-H Fluorination
(2023)[FeII(NCCH3)(NTB)](OTf)2 (NTB = tris(2-benzimidazoylmethyl)amine, OTf = trifluoromethanesulfonate) was reacted with difluoro(phenyl)-λ3-iodane (PhIF2) in the presence of a variety of saturated hydrocarbons, resulting in ... -
Aromatic and aliphatic hydrocarbon hydroxylation via a formally NiIV=O oxidant
(2023)The reaction of (NMe4)2[NiII(LPh)(OAc)] (1[OAc], LPh = 2,2′,2′′-nitrilo-tris-(N-phenylacetamide); OAc = acetate) with 3-chloroperoxybenzoic acid (m-CPBA) resulted in the formation of a self-hydroxylated NiIII-phenolate ... -
Manganese oxide nanosheets and a 2D hybrid of graphene-manganese oxide nanosheets synthesized by liquid-phase exfoliation
(2015)Manganese oxide nanosheets were synthesized using liquid-phase exfoliation that achieved suspensions in isopropanol with concentrations of up to 0.45 mg ml-1. A study of solubility parameters showed that the exfoliation ... -
Trendbericht Organische Chemie 2023
(2023)Polystyrolproben werden mit Eisen(III)chlorid und weißen LEDs zu Oligomeren und Benzoylprodukten; ein Wolframatkatalysator invertiert die Absolutkonfiguration an sp3-Kohlenstoffzentren; gelöstes Rätsel um eine symmetrieverbotene ... -
Bicyclo[1.1.1]pentane Embedded in Porphyrinoids**

Molecular Symmetry and Art: Visualizing the Near-Symmetry of Molecules in Piet Mondrian's De Stijl
(2024)Symmetry and shape are essential aspects of molecular structure and how we interpret molecules and their properties. We, as chemists, are comfortable with pictorial representations of structure, in which some nuance is ... -
Chirality induction to porphyrin derivatives co-confined at the air-water interface with silica nano-helices: towards enantioselective thin solid film surfaces
(2024)A supramolecular approach based on self-assembled structures allows the formation of large structured co-assemblies based on chiral and achiral compounds with original physicochemical features. In this contribution, an ... -
