Interfacial AIE for Orthogonal Integration of Holographic and Fluorescent Dual‐Thermosensitive Images
Orthogonal integration of thermosensitive images is of vital significance for advanced anticounterfeiting, which however remains formidably challenging due to the trade‐off that facile thermoresponse needs easy molecular motion while robust imaging requires molecular restriction. Herein, a viable ap...

description | Orthogonal integration of thermosensitive images is of vital significance for advanced anticounterfeiting, which however remains formidably challenging due to the trade‐off that facile thermoresponse needs easy molecular motion while robust imaging requires molecular restriction. Herein, a viable approach is demonstrated to tackle the challenge by in situ fixing a predesigned aggregation induced emission luminogen (AIEgen) at the polymer/liquid crystal (LC) interface via precisely controlled interfacial engineering, in which the AIEgen is enriched in LC phases during polymerization induced phase separation and subsequently driven to the interface by the interfacial thiol‐ene click reaction. Crosstalk‐free integration of holographic and fluorescent dual‐thermosensitive images with high sensitivity, high contrast ratio, and robust performance is successfully realized in a single unit, attributed to the simultaneously LC‐facilitated AIEgen molecular motion and polymer‐restricted AIEgen diffusion at the interface. The exciting characteristics of these orthogonally integrated dual images will enable them to prevent illegal replication and thus are expected to be promising for high‐security‐level anticounterfeiting applications. |
