“…Aggregate-induced emission (AIE) materials − have emerged as a transformative class of fluorophores, presenting a paradigm shift from traditional counterparts. The distinctive attribute of AIE materials lies in their heightened brightness, particularly when in the aggregated state, providing an enduring and intense fluorescence signal crucial for extended imaging investigations. − The robust brightness is complemented by increased photostability, ensuring sustained performance over prolonged durations and circumventing issues of signal degradation.…”

Achieving high‐performance luminescence for underwater bonding remains a significant challenge in materials science. This study addresses this issue by synthesizing a luminescent material based on an aggregation‐induced emission (AIE) monomer and copolymerizing it with lipoic acid (LA) to create an AIE supramolecular polymer. The resulting copolymer exhibits strong fluorescence under ultraviolet (UV) irradiation at 365 nm due to the AIE of TPEE and enables underwater adhesion. The P(LA‐TPEE) polymer demonstrates potential for digital encryption and decryption of quick response (QR) codes underwater. Furthermore, it can dissolve well in anhydrous ethanol, producing an environment‐friendly and super waterproof adhesive. Most notably, the P(LA‐TPEE) solution can be sprayed on human skin, creating an invisible tattoo that only became visible under UV light due to the hydrogen bond (H‐bond) and π–π structures. This smart tattoo can be quickly wiped away with alcohol, avoiding the painful and harmful process of tattoo removal. It can also be repeatedly applied to draw the preferred tattoo pattern. This AIE supramolecular polymer shows great potential in underwater adhesion and repair, underwater message encryption, and non‐toxic and painless invisible tattooing. Overall, this study provides a valuable approach for material design in the future.

The rapid development of mechano‐responsive fluorescence has been driven by its promising applications in the fields of sensors, information encryption, and anti‐counterfeiting. However, designing mechanophores that can exhibit fluorescence changes under relatively low force remains challenging. In this study, a mechano‐responsive fluorescent gel was developed using a tetraphenylethylene derivative as a cross‐linker, producing a dynamic covalent network that exhibits increased fluorescence under tensile stress. Based on controlled experimental studies and molecular modeling calculations, the fluorescence enhancement by external forces was attributed to the restriction of intramolecular motion in tetraphenylethylene by macromolecular chain orientation. In time‐dependent experiments, due to the exchange of dynamic covalent bonds, the stress relaxation and the decrease in fluorescence intensity of the gel at fixed strain occurred simultaneously, demonstrating the potential of this fluorescence as an indication of internal stress through aggregation‐induced emission (AIE) type mechanophore.
