Hydrogen‐Bond‐Anchored Metal‐Free Cationic TADF Glassy Scintillators for High‐Resolution Dynamic X‐Ray Imaging
Organic glassy scintillators offer a promising platform for scalable X‐ray imaging owing to their optical transparency and melt processability. However, their performance is often limited by inefficient triplet‐exciton utilization and poor condensed‐phase stability. Although flexible side chains or rotatable units...
