Fabrication of a new fluorescent film and its superior sensing performance to N-methamphetamine in vapor phase

- A fluorescent film with porous networked structures was fabricated.
- Fast, selective, and highly sensitive detection to N-methamphetamine(MAPA) in vapor phase was realized.
- Sensing performances strongly depend on adjusting the molecular assembly and molecular energy level.
- A conceptual MAPA detector based on the fluorescent film was developed, representing its potential for practical applications.
