| 제목 | Synthesis and optical sensor activitys of anthracene derivatives for detecting proton and water |
| 초록 | This paper describes the synthesis and optical sensing properties of fluorescence sensors (I and II) for proton and water. Sensor I and II were prepared by the attachment of a guanidine moiety to anthracene and applied as fluorescent pH sensors and water sensors. The fluorescence intensities of sensor I and II decreased with increasing pH values in the pH range between 11 and 13. The sensing mechanism was explained by the photoinduced electron transfer process. Sensors I and II were also useful as optical sensors for detecting the trace amount of water content in water-miscible organic solvents such as EtOH, CH3CN, DMF, THF and 1,4-dioxane. The fluorescence intensities of sensor I and II increased with increasing water content in organic solvents. The nitrogen atom of the sensor was protonated in the presence of water in organic solvents and the PET was inhibited to restore fluorescence emission. |
