Time-Evolving Reversible Circularly Polarized Luminescence Enabled by Light-Fueled Dissipative Self-Assembly of Covalent Organic Frameworks

Key Points

The aim is to develop dynamic covalent organic frameworks (COFs) capable of producing time-evolving reversible circularly polarized luminescence (CPL).
Utilized light-fueled self-assembly to create COF films.
Achieved photocontrollable and self-erasable vector luminescent signals for enhanced functionality.
Achieved a remarkable CPL value of approximately 0.035 among dynamic COF-based materials.
Demonstrated dual-mode anticounterfeiting through intelligent luminescent materials.

Abstract

≈0.035 is achieved, which is a remarkable value reported among dynamic COF-based CPL materials. Furthermore, films featuring photocontrollable, self-erasable vector luminescent signals are achieved for dual-mode anticounterfeiting. This work provides insight into the design of intelligent luminescent materials.
