The Insistence of Blackness and the Persistence of Antiblackness in Ireland

Australian Journal of Social Issues, EarlyView.
ABSTRACT This paper positions Ireland as a critical site for examining the insistence of blackness and an antiblackness created and sustained through Irish ethnonationalist imaginaries and exclusionary processes. Drawing on connected sociologies and Irish Black Studies, this enquiry argues that antiblackness in Ireland operates as a generational force,

Ambiphilic Ligand Stabilization of Aluminum(I) Fragments: Halides, Cations, and a Hydride

Angewandte Chemie, EarlyView.
Stabilization of elusive aluminum(I) halides in the framework of an ambiphilic ligand is reported. The unique bonding situation at the trigonal‐bipyramidal aluminum center is analyzed, and the coordination chemistry and Al(I)Br transfer reactivity of the complexes are presented.

Intracellular Delivery of Hydrophilic Glycans Using Superchaotropic Clusters

Angewandte Chemie, EarlyView.
Superchaotropic boron clusters are demonstrated to deliver hydrophilic glycans directly into mammalian cells, removing the need for acetylation and cytotoxic solvents such as DMSO. Azido glycans for metabolic oligosaccharide engineering, and trehalose, were delivered and the successful azido‐labelling of glycoproteins, cell surface glycans, and ...

Water, Alcohols, Amines, and Amides as Formal Hydrogen‐Atom‐Transfer Reagents Through Activation With Redox‐Active Lewis Acids

Angewandte Chemie, EarlyView.
Protic molecules containing strong O─H or N─H bonds typically resist hydrogen‐atom abstraction because of the high reactivity of the resulting heteroatom‐centered radicals. However, association of the protic molecules with redox‐active Lewis acids can provide powerful hydrogen‐atom donors or proton‐coupled‐electron‐transfer reagents.

Nitrogen Radical Photocatalysed Reduction of Nitrous Oxide

Angewandte Chemie, EarlyView.
This work offers the first example of reduction of the potent greenhouse gas N2O to the benign products N2 and O(Bpin)2 using a nitrogen‐based catalyst. The active catalyst is shown to be a nitrogen‐based radical which operates under photocatalytic conditions.

Engineering BN‐Doped Open‐Shell Polycyclic Hydrocarbons for Enhanced Photothermal Conversion and Therapy

Angewandte Chemie, EarlyView.
Two novel bonded BN‐doped polycyclic hydrocarbons BN‐Dira and BN‐Tetra with open‐shell character were rationally designed and synthesized. Their molecular structures were unambiguously confirmed by crystallographic analysis. Facilitated by their intense absorption in the NIR region, high PCE (83.6%) and good photothermal stability, BN‐Dira and BN‐Tetra

A Blue Emissive Heavy Atom‐Free Multiresonant Thermally Activated Delayed Fluorescent Emitter Shows Ultra‐Fast Reverse Intersystem Crossing

Angewandte Chemie, EarlyView.
The extended π‐system and low‐lying n‐π∗ transition endow DDOBDiKTa with a synergistic combination of strong spin‐orbit coupling, small reorganization energy and small ΔEST, enabling this blue boron‐nitrogen‐carbonyl hybrid emitter to achieve a fast kRISC of 6.34 × 106 s−1 together with OLEDs showing small efficiency roll‐off, with EQEmax/EQE10000 of ...

Unexpectedly Strong Electrostatic Screening in Nano‐Ion Solutions

Angewandte Chemie International Edition, EarlyView.
Colloidal probe AFM measurements reveal unexpectedly strong electrostatic screening in aqueous solutions of the polyoxometalates phosphotungstate [PW12O40]3−${[{\rm PW}_{12}{\rm O}_{40}]}^{3-}$ and silicotungstate [SiW12O40]4−$[{\rm SiW}_{12}{\rm O}_{40}]^{4-}$.
