Recent advances in preparation and applications of white circularly polarized luminescent materials

Abstract

White circularly polarized luminescence (WCPL) integrates the characteristics of circular polarization luminescence and broadband white emission, enabling chiroptical luminescence under photoexcitation or electroluminescence conditions. Recently, WCPL materials have attracted increasing attention from both academic and industrial communities due to their potential applications in a wide range of fields, including optical anti-counterfeiting, information storage, biomedical diagnostics, optical sensing, and next-generation optoelectronic devices. In this review, we systematically summarize recent advances in the design, synthesis, and application of WCPL-active materials. Particular emphasis is placed on three representative designing strategies of WCPL materials: polymer-based systems, multicomponent-doped systems and single-component systems. These approaches collectively highlight the diverse molecular design principles and structure–property relationships underlying efficient WCPL behavior. We believe that this review will provide valuable insights for researchers across various disciplines and inspire further exploration and innovation in this rapidly evolving field of chiral luminescent materials.
