Single-component color-tunable circularly polarized organic afterglow through chiral clusterization

Abstract

Circularly polarized organic afterglow (CPOA) with both long-lived room-temperature phosphorescence and circularly polarized luminescence is attracting great interest, but the development of multicolor-tunable CPOA in a single-component material remains challenging. Here, the authors report a strategy to achieve multicolor CPOA through chiral clusterization by inserting a chirality center into a non-conjugated organic cluster.
