| Abstract: | The photosensitive diamine 1,4-bis[2-(3-aminobenzoyl)vinyl]benzene(Ⅰ) was prepared by aldol condensation of 3-aminoacetophenone and terephthalaldehyde.The best conditions for synthetic process were optimized.Thus,3-acetylacetanilide and 4-acetamidobenzaldehyde were dissolved in ethyl alcohol with sodium hydroxide as catalyst and stirred at 0 ℃ for 3 h.The product was purified by recrystallization.Ⅰ was obtained in 86.4% yield and of 99.91% purity.Its structure was characterized by elementary analysis and IR spectrum. |
