Herein, we prepared two novel pairs of enantiomeric gold cluster complexes, AU₄PL₄/Au₄PD₄ and (Au₄L₄)_n/(Au₄D₄)_n with atomic precision. In Au₄PL₄/Au₄PD₄, the discrete chiral Au₄-based aggregation-induced emission (AIE) luminogens are separated by bulky substitutes. The corresponding aggregates are cyan-emitting with a photoluminescence quantum yield (PLQY) of 14.4%. Upon decreasing the size of the substituents, these chiral Au₄ clusters are strung together by inter-cluster Au-Au interactions, which cause a low-energy green emission from the aggregated (Au₄L₄)_n/(Au₄D₄)_n with a much higher PLQY of 41.4% and more intense circularly polarised photoluminescence (CPL) with a dissymmetry factor |g_PL| of 7.0 × 10⁻³. Using (Au₄L₄)_n/(Au₄D₄)_n, circularly polarised organic light-emitting diodes (CP-OLEDs) were for the first time fabricated with |g_EL| = |g_PL|. These findings signify that inter-cluster metallophilic interactions are a new and important type of driving force for AIE and crystallization-induced emission (CIE), suggesting great potential of CPL-active metal clusters in CP-OLEDs.

在此，我们以原子精度制备了两对新的对映体金簇复合物AU ₄ PL ₄ / Au ₄ PD ₄和（Au ₄ L ₄）_n /（Au ₄ D ₄）_n。在Au ₄ PL ₄ / Au ₄ PD _4中，离散的手性Au ₄基的聚集诱导发射（AIE）发光剂被庞大的替代物隔开。相应的聚集体发出蓝光，其光致发光量子产率（PLQY）为14.4％。随着取代基尺寸的减小，这些手性Au ₄簇通过簇间Au-Au相互作用串在一起，这导致聚集的（Au ₄ L ₄）_n /（Au ₄ D ₄）产生低能绿色发射_n的PLQY更高，为41.4％，并且圆偏振光致发光（CPL）强度更高，且具有不对称因子| g _PL | 的7.0×10 ^{- 3}。使用（Au首次用| ₄ L ₄） _n /（Au ₄ D ₄） _n制备圆偏振有机发光二极管（CP-OLED）。g _EL | = | g _PL |。这些发现表明，簇间的亲金属相互作用是AIE和结晶诱导发射（CIE）的一种新的重要类型的驱动力，表明CP-OLED中CPL活性金属簇的巨大潜力。
