## Title

- title: 'Au<sub>13</sub> Superatom Bearing Two Terpyridines at Coaxial Positions:
    Photoluminescence Quenching via Complexation with 3d Metal Ions'

## Description

- description: A gold cluster [Au13(dppe)5(EPTpy)2]3+ (dppe = 1,2-bis(diphenylphosphino)ethane,
    EPTpy-H = 4'-(4-ethynylphenyl)-2,2':6',2''-terpyridine) was synthesized by ligand
    exchange reaction of [Au13(dppe)5Cl2]3+. Single crystal X-ray diffraction analysis
    revealed that two terpyridyl moieties were σ-bonded to the coaxial positions of
    the icosahedral Au13 core. These two terpyridyl moieties were coordinated with
    3d metal ions M2+ (M = Co, Ni, Cu, Zn) in acetonitrile solution under ambient
    conditions. The photoluminescence (PL) of [Au13(dppe)5(EPTpy)2]3+ with quantum
    yield of 0.17 at ~780 nm was quenched almost completely by coordination with Co2+,
    Ni2+, and Cu2+, while the PL was not affected by Zn2+ coordination. The metal-dependent
    PL quenching behavior is ascribed to the difference in the electronic structure
    of the metal ions. The energy transfer from the Au13 chromophore to the coordinated
    Co2+, Ni2+, or Cu2+ with open electronic structure proceeds efficiently via an
    electron exchange mechanism, while the process is prohibited to Zn2+ with closed
    electronic structure.
