Symmetry Breaking in Chiral Gold Nanoclusters by Ansa‐Metallamacrocycles Strain

open access: yesAggregate, EarlyView.
In this work, we prepare a chiral Au11 nanocluster ligated by diphosphine ligand, Au11(dppp)5Cl3, which is induced by the unique ansa‐metallamacrocycle stain (the “Au─P─CH2CH2CH2─P─Au” staple). ABSTRACT Chiral nanomaterials have recently stimulated significant interest in both fundamental research and practical applications (e.g., nanoprobes for ...

Emerging Opportunities of Metal Nanoclusters for Photocatalytic Organic Synthesis

open access: yesAggregate, EarlyView.
Atomically precise metal nanoclusters have emerged as versatile photocatalysts for photo‐induced organic reactions. This review comprehensively summarizes recent advances in this cutting‐edge research field. We begin the discussion with a brief introduction of metal nanoclusters and the fundamental principles of photocatalysis.

Bright Circularly Polarized Electrochemiluminescence from Heterobinuclear IrIII–AuI Enantiomers

open access: yesAngewandte Chemie, EarlyView.
Efficient and bright circularly polarized electrochemiluminescence (CP‐ECL) is achieved in a class of enantiopure hetobinuclear iridium(III)–gold(I) complexes owing to the combination of high ECL efficiency with stability, good emission dissymmetry factor and high brightness, thus paving the way to the next‐generation of bright CP‐ECL probes.

Stacking‐Angle‐Manipulated Emission (SAME) in Anthracene‐Based Figure‐Eight Metallo‐Supramolecules

open access: yesAggregate, EarlyView.
Most strategies of tuning packing modes of chromophores are covalent synthesis without reversible features. Herein, we developed a customizable strategy to construct a series of figure‐eight supramolecules S1–S3 with different stacking angles of chromophores. The fluorescent properties were enhanced with stacking angles increased.
