Abstract
The present subject matter relates to a fluorescent compound having aggregation-induced emission (AIE) characteristics. The compound can be a rod-like chiral luminogen bearing a chiral moiety at one end and long aliphatic chains at an opposing end. The compound emits circularly polarized light or luminescence (CPL) in the aggregate state. For example, the compound does not exhibit a chiroptical signal when dispersed in solution, but demonstrates tunable CPL signals in the aggregate state.
