Evolution of Circularly Polarized Luminescence in Atomically Precise Silver Nanoclusters with Intrinsic Chirality.

ABSTRACT: Circularly polarized luminescence (CPL) is a powerful tool to probe the chiroptical properties of molecular systems in the excited state. Here, we demonstrate the evolution of excited-state chiroptical property in silver nanoclusters (NCs) by CPL measurements. The use of bidentate thiolate ligand, 1,3-benzenedithiol (BDT), with the aid of triphenylphosphine (PPh₃), affords racemic [Ag₂₉(BDT)₁₂(PPh₃)₄]^3- NCs (Ag₂₉ NCs) with intrinsic chirality in the exterior cage composed of a silver(I)-dithiolate coordination framework, that are separable by chiral column chromatography. We have recently reported that the post-synthetic modification of negatively charged Ag₂₉ NCs with a cationic silver(I) complex on th
