From Magic Size to Atomic Precision: Facile Synthesis of a CdTe Semiconductor Nanocluster

reported about three decades ago, thus filling the missing link in this family. The cluster features a zincblende core in a truncated tetrahedron shape. While the core is achiral, chirality emerges from the rotational stacking of surface ligands. The left and right enantiomers self-assemble into a highly ordered, atomically coherent cubic superlattice, leading to a rare racemic crystal coined as "kryptoracemate." This method provides an accessible platform for further atomic engineering of CdTe and related nanoclusters toward their target applications.
