Presented herein is a series of chain compounds based on pre-designed heterometallic aluminum-lanthanide (Al-Ln) AlLn molecular rings. Their photoluminescence quantum yield (PLQY) with Eu (30.41%) and Tb (41.44%) is at a high level among the clusters containing four Ln ions. This study significantly extends the family of Al-Ln heterometallic clusters and demonstrates the synergistic effect of heterometallic ions in enhancing their properties.
