摘要

A facile strategy is fabricated for multicolor luminescent films from blue to red by doping an intramolecular charge transfer (ICT)-active aggregation-induced emission luminogen (AIEgen) into a polar bifuran-based polyester.

Abstract

Multicolor luminescent materials have attracted considerable attention for their applications in information storage

encryption

and flexible displays. However

these materials often suffer from cumbersome synthesis and poor film-form ability. Herein

we report a facile strategy to fabricate multicolor luminescent films by doping an intramolecular charge transfer (ICT)-active aggregation-induced emission luminogen (AIEgen) into highly polar bifuran-based polyester. In combination with the ICT effect of the AIEgen

the distinct energy transfer efficiency between the polyester and the AIEgen achieves the wide-range emission color change from blue to red in the doped films. Furthermore

the AIEgen exhibits reversible pH-responsiveness and irreversible photocyclization under 365 nm UV light. Accordingly

a nine-grid and “dragon/QR code” patterns are designed using these doped films

demonstrating their potential in advanced information encryption and storage. This work not only provides a new perspective on the fabrication of multicolor luminescent materials

but also paves the way in information storage

data encryption

and other advanced technologies.
