Chiral recognition via symmetry-dependent luminescence in zero-dimensional hybrid copper halides.

ABSTRACT: Chiral recognition through fluorescence changes enables the rapid and sensitive determination of enantiomers. However, the rational design and synthesis of fluorescent probes for efficient chiral recognition remain a challenge. Here we present a novel platform for chiral recognition based on zero-dimensional hybrid copper halides with unique symmetry-dependent properties. The use of mesomeric 1,2-diaminocyclohexane (DACH) ligands promotes the formation of centrosymmetric, non-luminescent Cu₂I₆^4- units. The incorporation of enantiopure S- or R-DACH ligands into these mesomeric compounds breaks their symmetry, spontaneously transforming them into chiral compounds and generating Cu₄I₆^2- units that exhibit intense circularly pol
