| 英文摘要 | Real-time and accurate detection of ph in aqueous solution is of great significance in chemical, environmental, and engineering-related fields. we report here the use of 8-hydroxyquinoline-functionalized covalent organic framework (cof-hq) for dual-mode ph sensing. in the fluorescent mode, the emission intensity of cof-hq weakened as the ph decreased, and also displayed a good linear relationship against ph in the range from 1 to 5. in addition, cof-hq showed discernible color changes from yellow to black as the acidity increased and can be therefore used as a colorimetric ph sensor. all these changes are reversible and cof-hq can be recycled for multiple detection runs owing to its high hydrolytical stability. it can be further assembled into a mixed matrix membrane for practical applications. |
