| 논문초록 | Designed carbazole-based novel fluorophores exhibit a sensitive response to toxic and explosive nitroaromatic compounds via complexation, whose detection sensitivity or selectivity can be demonstrated by comparing their emission-quenching rate constant or the adoption of similar-structured aromatic compounds as a negative control. The results of time-resolved fluorescence spectroscopy indicate that the static quenching mechanism is involved in NAC detection. In addition, it has been demonstrated by UV-Vis. and NMR spectroscopy studies that the quenching of the devised fluorophores originated from complexation with NACs. The difference in the detection sensitivity of the fluorophores for the corresponding NACs can be connected to both the different steric effects and the degree of energy off-set between the fluorophores and the NACs. A porous membrane-type detection platform was found to be effective even at 1 ppb within 5 s. |
