Recent advances in organic stimuli-responsive tunable circularly polarized luminescence materials

Abstract

Circularly polarized luminescence (CPL) materials have manifested extensive application prospects in domains owing to their distinctive chiral optical properties, such as three-dimensional display, information encryption and optical sensing. However, conventional CPL materials with fixed emission wavelengths and polarization directions struggle to meet the growing demand for multifunctional materials. In recent years, organic stimuli-responsive tunable CPL materials have attracted significant attention due to their reversible and dynamic properties. These materials can realize the dynamic regulation of the emission wavelength, polarization direction or luminescence efficiency under external stimuli (light, temperature, pH, ions, etc). This review systematically summarizes the design principles, regulatory mechanisms, and potential applications of organic stimuli-responsive tunable CPL materials with different types of stimuli.
