Fluorescent Sensors for Nitroaromatic Compounds Based on the Comb-Like Polysiloxane-Acrylate
A functional polysiloxane monomer, with a double bond and a fluorophore pyrene at each end of the polysiloxane chain, respectively, was synthesized. Copolymerize this functional monomer with other acrylates in emulsion, we got a comb-like polymer in which pyrene fluorophore is at the end of each polysiloxane side-chain. This polymer shows great advantage in sensing performance for 2,4-dinitrotoluene (DNT) over its analog that was prepared just by mixing pyrene with pure polyacrate emulsion.
