The novel butterfly-shaped tetracarboxylic acid [9,9'-methylene-bis(9-methylfluorene-2,7-dicarboxylic acid), H4L] featuring a co-facial bifluorene core was designed and synthesised. Reactions of H4L with CdII produced the luminescent supramolecular frameworks 2 and 3, with different dimensionality and wingspan of L4–. The solid-state emission prope...

The rational construction of efficient and low-cost electrocatalysts for the hydrogen evolution reaction (HER) is critical to seawater electrolysis. Herein, trimetallic heterostructured core-shell nanoboxes based on Prussian blue analogues (Ni-Co@Fe-Co PBA) were synthesized using an iterative coprecipitation strategy. The same coprecipitation proce...

Following the successful introduction of two benign solvents for cleaving protected acid peptide fragments from 2-chlorotrityl chloride (2-CTC) resin, there is a need to green the cleavage process for obtaining protected peptide amide fragments. In this work, p-xylene and toluene are introduced as greener alternates to dichloromethane (DCM) for pre...

Ethylene is an important feedstock in the chemical industry, but currently requires production from fossil resources. The electrocatalytic oxidative decarboxylation of succinic acid offers in principle an environmentally friendly route to generate ethylene. Here, a detailed investigation of the role of different carbon electrode materials and chara...

The surface energy and surface chemistry of a crystal are of great importance when designing particles for a specific application, as these will impact both downstream manufacturing processes as well as final product quality. In this work, the surface properties of two different quercetin solvates (quercetin dihydrate and quercetin DMSO solvate) we...

Abstract. A novel class of readily accessible tartramide ligands has been demonstrated to promote copper-catalysed N-arylation under mild conditions. In addition, the coupling protocol employs cheap and readily available pre-catalyst, ligand, and base (NaOH), and overcomes many current limitations often associated with Ullmann coupling: it can be r...

The mechanism and dynamics of the CO2 reduction reaction (CO2RR) remain poorly understood, which is largely caused by mass transport limitations and lack of time-correlated product analysis tools. In this work, a custom-built gas accessible membrane electrode (GAME) system is used to comparatively assess the CO2RR behavior of Au and Au−Cu catalysts...

Iron nitride (Fe3N) and iron carbide (Fe3C) nanoparticles can be prepared via sol–gel synthesis. While sol–gel methods are simple, it can be difficult to control the crystalline composition, i.e., to achieve a Rietveld-pure product. In a previous in situ synchrotron study of the sol–gel synthesis of Fe3N/Fe3C, we showed that the reaction proceeds a...

Under mild conditions of room temperature and pressure, and using either pure oxygen or air, aldehydes are converted using a heterogeneous Fe–N/C catalyst to produce the corresponding organic peroxy acid and acylperoxy radicals, which forms the epoxide from cyclohexene with high yield (91% for isobutyraldehyde in O2). Real-time monitoring of the ra...

A novel radiolabelling method exploiting 11C-dithiocarbamate ligands has been used to generate 11C-labelled Au(I), Au(III), Pd(II) and Pt(II) complexes in high radiochemical yields (71–99%). Labelled complexes were prepared in a rapid one-pot procedure via the substitution reaction of 11C-dithiocarbamate ligands with appropriate transition metal ch...
