Abstract

A study was conducted to demonstrate real-time, ultrasensitive detection of 1,3,5-Trinitro-1,3,5-triazine (RDX) vapors using conjugated network polymer thin films. The sensitivity of the film and its response time were were evaluated using both static and real-time fluorescence quenching experiments by introducing RDX from the solution or vapor phase. These optimized tris-(phenylene)vinylene (TPV) films displayed a measurable response to RDX vapor in 10 seconds and to attogram amounts of HMX introduced from solution, making these polymer films of interest for security applications.
