Molecular Engineering of Excited-State Dynamics via ICT toward a Cross-Reactive Single-Fluorophore Array for Discriminative Sensing of VOCs

Key Points

• The aim is to develop high-performance fluorescent sensors that can effectively detect volatile organic compounds (VOCs) in real-time.
• Developed fluorescent film-based sensors (FFSs) to enhance sensing capabilities.
• Engineered fluorescent units to address challenges like aggregation-caused quenching.
• Conducted real-time detection tests for a variety of VOCs.
• Improved photostability and resistance to aggregation was observed in the new fluorescent units.
• The fluorophore array demonstrated the ability to discriminate between different VOCs.
• Results indicated a significant enhancement in detection sensitivity compared to conventional materials.
