ABSTRACT Photocurable polymers have gained widespread application due to their advantages such as rapid curing, high precision, good biocompatibility, and environmental safety. The monomeric conversion efficiency and generated polymeric polarity change during the photocurable process directly affect the final performance of functional polymers. Therefore, exploring a feasible strategy to achieve real‐time, in situ, and synchronous monitoring of monomeric conversion and polymeric polarity change is of particular significance, but currently, there is a lack of such a method to realize the above purpose. Herein, we designed and synthesized a class of phenazine‐based dual‐responsive fluorescent probes with aggregation‐induced emission and intramolecular charge transfer effect, achieving simultaneously in situ visual real‐time monitoring of monomeric conversion efficiency and polarity change of photocurable polymer. In addition to the aforementioned behaviors, these synthetic probes could produce type I reactive oxygen species, further realizing broad‐spectrum antibacterial behavior containing Staphylococcus aureus ( S. aureus ), Gram‐negative bacterium Escherichia coli ( E. coli ), and Methicillin‐resistant Staphylococcus aureus (MRSA) because of the photodynamic therapy. This work developed an effective method for achieving in situ visual real‐time detection of the photocurable process, and prepared polymeric film could be used to achieve excellent antibacterial effect, which finally ensured the function of promoting the healing of bacterial‐infected wounds.
