| titleOfInvention | Amide derivative of rhodamine B and preparation method thereof |
| abstract | The invention provides an amide derivative of rhodamine B and a preparation method thereof. In the method, rhodamine B dye with carboxyl on 1-site is used as a matrix and reacts with amine to generate the rhodamine B amide derivative. The method comprises the following steps of: dissolving the rhodamine B with carboxyl on the 1-site into a dry organic solvent, adding alkyl amine into the organic solvent, reacting the mixture under the protection of inert gas, and removing the solvent by reduced pressure distillation; and purifying the obtained substrate by using eluent through a chromatographic column, acidifying the purified substrate, drying the acidified product under vacuum, and removing the solvent to obtain a target product of the rhodamine B amide derivative. The amide derivative of the rhodamine B provided by the invention has the following structure. |
