- Abstract
Due to the ubiquity of chirality in nature, chiral self‐assembly involving self‐sorting behaviors has remained as one of the most important research topics of interests. Herein, starting from a racemic mixture of SEG‐based (SEG=SEGPHOS) chlorogold(I) precursors, a unique chiral butterfly‐shape hexadecanuclear gold(I) cluster (Au16) with different ratios of RSEG and SSEG ligands is obtained via homoleptic and heterochiral self‐sorting. More interestingly, by employing different chlorogold(I) precursors of opposite chirality (such as RSEG‐Au2 and SBIN‐Au2 (BIN=BINAP)), an unprecedented heteroleptic and heterochiral self‐sorting strategy has been developed to give a series of heteroleptic chiral decanuclear gold(I) clusters (Au10) with propellor‐shape structures. Heterochiral and heteroleptic self‐sorting have also been observed between enantiomers of homoleptic chiral Au10 clusters to result in the heteroleptic chiral Au10 clusters via cluster‐to‐cluster transformation. Incorporation of heteroleptic ligands is found to decrease the symmetry from S4 of homoleptic meso Au10 to C2 of heteroleptic chiral Au10 clusters. The chirality has been transferred from the axial chiral ligands and stored in the heteroleptic gold(I) clusters.
