Chiral luminescent radicals: Based on the origin of chirality, we classified the currently reported chiral luminescence radicals into three categories, intrinsic chiral luminescent radicals, luminescent radicals with chiral substitutions, and field-regulation-induced chiral luminescent radicals. This brief review of their properties aims to provide basic guidelines for the development of these systems and to support further development of novel chiral luminescent radical systems.

Abstract

Chiral luminescent materials are a class of materials capable of emitting circularly polarized light (CPL). Radicals are unique open-shell compounds with exceptional photoelectromagnetic properties that can be exploited in constructing novel chiral luminescent materials. This Concept discussed three main catalogues for producing organic CPL radicals, intrinsic chiral luminescent radicals, luminescent radicals with chiral substitutions, and field-regulation-induced chiral luminescent radicals. The brief review of their properties aims at providing basic guidelines and supporting further development of novel chiral luminescent radical systems.
