Under acid conditions, the protonation of BP4VA generates a rapid change with high color contrast from yellow to red and a fluorescence switch between bright green and weak red emission.

Furthermore, utilizing rapid and remarkable pH-responsive properties of BP4VA/PAS hydrogels, we successfully demonstrated its applications in biomimicry, camouflage, and multistage information encryption.
