| 제목 | A highly sensitive fluorescent polymer for explosive nitroaromatic compounds sensing |
| 초록 | We have attempted to synthesize of a new fluorescent sensor based on oxadiazole polymer which showed a high sensitivity for explosive nitroaromatic compounds, such as 2,4,6-trinitrophenol, 2,4-dinitrotoluene, and m-dinitrobenzene by a decrease in the photoluminescence intensity at the around 520 nm and an increase in the UV absorption in the near UV-region in chloroform. The polymer (Mn = 1.0 x 104, PDI = 2.0) exhibited a good solubility in common organic solvents such as THF and chloroform, and a remarkably large Stokes shift in fluorescence spectrum due to excited-state intramolecular proton transfer.

Absorption and photoluminescence spectra change of OXD copolymer upon addition of picric acid (0 M, 3.3 x 10-5 M, 6.6 x 10-5 M, 1.0x10-4 M at UV and 0 M, 5.0 x 10-5 M, 1.0 x 10-4 M, 4.0 x 10-4 M at PL) in CHCl3. Ksv = 7.4 X 104. |
