| titleOfInvention | Carbon quantum dot modified by hydroxypyridone compound and preparation and application thereof |
| abstract | The invention relates to a preparation method of carbon quantum dots modified by hydroxypyridones compounds, which comprises the following steps: reacting hydroxyl protected hydroxypyridone compound with amino functionalized carbon quantum dots under the action of a cross-linking agent at 20-40 ℃, and after the reaction is completed, carrying out reduction reaction in hydrogen under the action of a Pd/C catalyst to remove protective groups, thereby obtaining the carbon quantum dots modified by the hydroxypyridone compound, wherein the hydroxypyridone compound is 3, 4-hydroxypyridone and/or 3, 2-hydroxypyridone. The carbon quantum dot modified by the hydroxypyridones compound can be used for detecting uranyl ions, and is high in ion selectivity, short in response time, stable in response signal and environment-friendly. |
