More is better: aggregation induced luminescence and exceptional chirality and circularly polarized luminescence of chiral gold clusters

Abstract

The influence of the aggregation-induced emission (AIE) effect on the luminescence and the chirality of two chiral Au clusters (R)-1 and (S)-1 was well demonstrated. Their solid states exhibited extremely bright phosphorescence with quantum yields above 70%. The two clusters were free of luminescence and chirality in diluted solution. Meanwhile, the formation of aggregate states could not only induce both the luminescence and the chirality, but also further facilitate their enhancements, which resulted in the output and the modulation of desirable circularly polarized luminescence.
