Vapochromic features of new luminogens based on julolidine-containing styrene copolymers

In this work, the devising, synthesis and characterization of a new polymerizable FMR based on a hydroxymethylmethacrylate monomer functionalized by a cyanovinyl-julolidine moiety will be described. Copolimerization of the novel fluorophore with styrene provides new fluorescent vapochromic polymers with enhanced VOCs sensitivity owing to the covalent bonding between the fluorophore and the host matrix. Vapochromic behaviour of the new materials upon exposure to different VOCs will be discussed.
