Thermo‐Responsive Tri‐State Photonic Crystals

open access: yesAdvanced Science, EarlyView.
Tri‐state photonic crystals combine thermochromic structural color, fluorescence, and afterglow via far‐field absorption tuning, bypassing the efficiency‐lifetime trade‐off of TS‐FRET. This enables dynamic, high‐capacity anti‐counterfeiting with tunable optical states.

Efficient Red Light–Driven Singlet Oxygen Photocatalysis with an Osmium‐Based Coulombic Dyad

open access: yesAngewandte Chemie, EarlyView.
Red light‐absorbing bichromophores with straightforward preparation and superior photocatalytic activity were developed. Spectroscopic studies provided deep insights into the intra‐ion‐pair energy transfer key step and the novel approach. Abstract Photoactive osmium complexes are widely used sensitizers for the generation of singlet oxygen because they
