Emissive Oxidase-Like Nanozyme Based on Organic Molecular Cage

In this work, we introduced four “claw-like” units dipicolylamine (DPA) to a tetraphenylethylene (TPE)-based organic molecular cage (DPA-TPE-Cage). Coordinated with Zn2+ ions, the obtained ZnDPA-TPE-Cage exhibited aggregation induced emission (AIE) effect and oxidase-like properties, which endowed it the ability to selectively image and kill Gram-positive bacteria S. aureus efficiently.
