Using salicylaldehyde (2-hydroxyacetophenone), propylamine (n-butylamine), boric acid in the solution of acetonitrile as raw materials, compound 1, 2, 3 and 4 have been prepared by microwave-assisted one-pot method. In the microwave conditions of reaction power 800 w and reaction temperature 80 oC under a short reaction time, large amount of the compounds have been prepared and the spectral properties of these compounds have been studied. For the different of the substituent on C connected to N, there were blue, bluish violet, blue-green fluorescence on those compounds under the irradiation of ultraviolet light. This paper gives the best microwave synthesis conditions of for such compounds All the compounds except for 5,6 have obviously fluorescence effect under the irradiation of ultraviolet light. Compounds containing fluorine or amino substituents have relatively good recognition effect for monovalent ion. |
