Highly Selective Non-Covalent On-Chip Functionalization of Layered Materials
(2021)Non-covalent functionalization of layered 2D materials is an essential tool to modify and fully harness their optical, electrical, and chemical properties. Herein, a facile method enabling the selective formation of ... -
Highly sensitive, transparent, and flexible gas sensors based on gold nanoparticle decorated carbon nanotubes
(2013)We report on a high performance flexible and transparent chemical sensor based on functionalised single-walled carbon nanotubes (SWCNTs). The SWCNT films were spray-deposited on transparent and flexible plastic substrates, ... -
Highly Strained Tertiary sp3 Scaffolds: Synthesis of Functionalized Cubanes and Exploration of Their Reactivity under Pd(II) Catalysis
(2015)A series of chemically distinct, highly strained, activated cubane scaffolds was synthesized through optimization of the metal-halogen exchange reactions of iodinated cubane derivatives. This included the first reported ... -
Highly substituted 2,3,7,8,12,13,17,18-octaethylporphyrins with meso aryl residues
(2010)Highly substituted porphyrin-bearing meso aryl groups are useful compounds for optical applications and for studies on the interrelationship between the substituent pattern, macrocycle conformation and physical properties. ... -
Highly tunable arylated cinchona alkaloids as bifunctional catalysts
(2012)We report the design and evaluation of a library of chiral bifunctional organocatalysts in which the distance between the catalytically active units can be systematically varied. -
Hole localization in Al doped silica: A DFT+U description
(2006)Despite density functional theory (DFT) being the most widely used ab initio approach for studying the properties of oxide materials, the modeling of localized hole states in doped or defective oxides can be a challenge. ... -
Homogeneously dispersed multimetal oxygen-evolving catalysts
(2016)Earth-abundant first-row (3d) transition-metal-based catalysts have been developed for the oxygen-evolution reaction (OER); however, they operate at overpotentials significantly above thermodynamic requirements. Density ... -
Homolytic products from heterolytic paths in H2 dissociation on metal oxides: The example of CeO2
(2014)Mechanisms for H2 dissociation on metal oxides have been typically inferred from the infrared spectra of reaction products on the basis of the presence or lack of M–H fingerprints. Here, we demonstrate by means of ... -
Huisgen-based conjugation of water-soluble porphyrins to deprotected sugars: Towards mild strategies for the labelling of glycans
(2014)Fully deprotected alkynyl-functionalised mono- and oligosaccharides undergo CuAAC-based conjugation with water-soluble porphyrin azides in aqueous environments. The mild reaction conditions are fully compatible with the ... -
Hydrogels: Soft matters in photomedicine
(2019)Photodynamic therapy (PDT), a shining beacon in the realm of photomedicine, is a non‐invasive technique that utilizes dyebased photosensitizers (PSs) in conjunction with light and oxygen to produce reactive oxygen species ... -
Hydrogen Atom Transfer Oxidation by a Gold-Hydroxide Complex
(2020)AuIII-oxygen adducts have been implicated as intermediates in homogeneous and heterogeneous Au oxidation catalysis, but their reactivity is under-explored. Complex 1, ([AuIII(OH)(terpy)](ClO4)2, (terpy = 2,2':6',2-terpyridine), ... -
Hydrogen bonding interactions and supramolecular networks of pyridine-aryl based thiosemicarbazides and their Zn(II) complexes
(2013)The synthesis of five pyridyl derived thiosemicarbazides, 1-5, is presented. All five were formed in a single step from 2-hydrazinopyridine with commercially available isothiocyanates using microwave assisted synthesis. ... -
Hydrogen bonding pattern in six derivatives of 2,4-dimethylpyrrole
(2005)The crystal and molecular structures of 4-ethyl-3,5-dimethylpyrrole-2-carbaldehyde, C10H15NO, (I), benzyl 3,5-dimethylpyrrole-2-carboxylate, C14H15NO2, (II), benzyl 4-acetyl-3,5-dimethylpyrrole-2-carboxylate, C16H17NO3, ... -
Hydrous Nickel Oxide: Redox switching and the oxygen evolution reaction in aqueous alkaline solution
(2012)The redox switching reaction and the oxygen evolution reaction at multi-cycled nickel oxy-hydroxide films in aqueous alkaline solution are discussed. The hydrous oxide is considered as a porous assembly of interlinked ... -
A hydroxamic-acid-containing nucleoside inhibits DNA repair nuclease SNM1A
(2019)Nine modified nucleosides, incorporating zinc-binding pharmacophores, have been synthesised and evaluated as inhibitors of the DNA repair nuclease SNM1A. The series included oxyamides, hydroxamic acids, hydroxamates, a ... -
Hyper-crosslinked 4-amino-1,8-naphthalimide Tröger’s base containing pyridinium covalent organic polymer (COP) for discriminative fluorescent sensing of chemical explosives
(2020)A new hyper-crosslinked 4-amino-1,8-naphthalimide Tröger’s base containing pyridinium covalent organic polymer, TBNap-COP, was synthesised and employed as a ‘turn-off’ fluorescent chemosensor for nitroaromatic explosives. ... -
