Engineering intelligent chiral silver cluster‐assembled materials for temperature‐triggered dynamic circularly polarized luminescence

Aggregate
The development of stimuli‐responsive circularly polarized luminescence (CPL) materials is quite attractive but challenging. Here, a pair of atomically precise enantiomers R/S‐Ag20 nanoclusters has been synthesized using chiral acid ligands.
