New fluorescent tools for the development of advanced vapochromic films based on thermoplastic polymers

[excerpt from the abstract]: The harmful effects of Volatile Organic Compounds (VOCs) demand simple sensitive, selective and cost effective sensors for their detection. Considering this fact, the sensing ability of the fluorescent molecules for the detection of VOCs is demonstrated in this work. In particular, here in we investigated the vapochromic behaviour of special fluorescent molecules known as fluorescent molecular rotors (FMRs), sensitive to both viscosity and polarity of the environment.
