Electrochemical Switch‐On of Nonlinear Optical Response in a Nitro‐Functionalized Arylimido‐Polyoxometalate

Angewandte Chemie, EarlyView.
Reducing a nitro‐derivatized arylimido‐polyoxometalate (POM) reversibly switches on its second‐order NLO response, contrasting with prior donor‐functionalized systems that switch off upon reduction. Attenuation of charge‐transfer (CT) to the POM upon reduction gives a more strongly dipolar imido/π‐bridge to ─NO2 CT, signal enhancement of up to 15× (β ...

Tailoring Photochromism Beyond Human Eye Visibility: On/Off Switchable NIR Absorption in an Aluminosilicate

Angewandte Chemie, EarlyView.
A new photochromic material was developed. Its on/off‐switchable absorption band is situated completely outside the human eye's visibility, in the near‐infrared (NIR) region, a feature never reported before. The photochromism mechanism in this aluminosilicate is elucidated by combining experimental as well as computational results, and the material's ...

Structural Control of Dual Emission in Coumarin Fluorophores for Visualizing Protein Droplet Maturation

Angewandte Chemie, EarlyView.
A coumarin‐based dual‐emission fluorophore was designed to visualize the maturation of protein liquid droplets. Upon covalent conjugation to droplet‐forming proteins, ratiometric fluorescence imaging allowed real time monitoring of droplet maturation. This probe is applicable to the analysis of droplet formation and maturation mechanisms, as well as to

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

Bond Length as a Unified Descriptor for Stable Iodine Battery

Angewandte Chemie, EarlyView.
Charge transfer induced by the interactions between iodine and ligands leads to the elongation of the I–I bond. This resulting bond length correlates directly with coordination strength, serving as a unified descriptor for the rational design of both cathode hosts and electrolyte components.

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 ...
