Acid-Induced "Turn-On" Fluorescence of β-Aminoacrylate-based Molecule and Polymers Toward Anti-Counterfeiting Applications

Key Points

• This research aims to investigate the fluorescence response of β-aminoacrylate-based molecules when exposed to acid, exploring its potential for anti-counterfeiting.
• Synthesis of β-aminoacrylate-based low-molecular motifs and polymers
• Exposure to acidic conditions to induce fluorescence changes
• Characterization of formed dihydropyridine derivatives
• A significant fluorescence 'turn-on' effect was observed upon acid exposure.
• Dihydropyridine derivatives were successfully formed during the process.
• The findings suggest a viable application in anti-counterfeiting technology.
