Crown-hydroxylamines
Despite the rich coordination chemistry, hydroxylamines are rarely used as ligands for transition metal coordination compounds. Here we designed macrocyclic poly-N-hydroxylamines (crown-hydroxylamines) that form complexes containing a d-metal ion and coordinate by up to six hydroxylamine fragments.
Direct time-resolved observation of surface-bound carbon dioxide radical anions on metallic nanocatalysts
A comprehensive understanding of the catalytic CO2 reduction mechanism has been limited by challenging direct time-resolved observation of the elementary steps. Here, we use pulse radiolysis to observe the stabilization processes towards well-defined nanoscale metallic sites.
The (w)hole story
Dissipative structures are governed by non-equilibrium thermodynamics. Here, we describe a size-dependent transition of active droplets into active spherical shells–a dissipative structure that originates from reaction-diffusion gradients.
Single-molecule fluorescence imaging and sequencing of single synthetic polymers
Microscopic sequences of synthetic polymers are critical to polymer properties, but are generally unavailable from traditional characterizations. Here, we achieved imaging of single synthetic polymers with single-monomer resolution and sequencing of synthetic copolymers for the first time.
Double Boron–Oxygen-Fused Polycyclic Aromatic Hydrocarbons: Skeletal Editing and Applications as Organic Optoelectronic Materials
The development of chemically diverse boron-oxygen-fused polycyclic aromatic hydrocarbons has been limited by their synthetic complexity. Here, authors report a one-pot strategy for their facile synthesis and demonstrate their potential as ultralong afterglow and host materials for deep-blue OLEDs.
