资源简介：
A general strategy, using mixed ligands,
is utilized to synthesize
atomically precise, intrinsically chiral nanocluster [Ag78(DPPP)6(SR)42] (Ag78) where DPPP
is the achiral 1,3-bis(diphenyphosphino)propane and SR = SPhCF3. Ag78 crystallizes as racemates in a centric space
group. Using chiral diphosphines BDPP = 2,4-bis(diphenylphosphino)pentane,
the enantiomeric pair [Ag78(R/S-BDPP)6(SR)42] can be prepared with 100% optical purity. The chiral diphosphines
gives rise to, separately, two asymmetric surface coordination motifs
composed of tetrahedral R3PAg(SR)3 moieties.
The flexible nature of C–C–C angles between the two
phosphorus atoms restricts the relative orientation of the tetrahedral
R3PAg(SR)3 moieties, thereby resulting in the
enantiomeric selection of the intrinsic chiral metal core. This proof-of-concept
strategy raises the prospect of enantioselectively synthesizing optically
pure, atomically precise chiral noble metal nanoclusters for specific
applications.
