以苯肼、乙酰乙酸乙酯和咔唑为原料,合成了一种含酰基吡唑啉酮和咔唑双光功能基元的新型席夫碱——1-苯基-3-甲基-4-苯甲酰基-吡唑啉酮-5-缩N-对氨基苄基咔唑(6),其结构经^1H NMR和IR确证;采用UV-vi。对其电子结构进行了初步研究,与酰基吡唑啉酮或咔唑功能基元相比,6表现出特殊的电子结构。
A novel Schiff base containing two optical functional blocks, 1 -phenyl-3-methyl-4-benzoyl- 5-pyrazolone-N-benzyl-carbazole(6), was synthesized from phenylhydrazine, ethyl acetoacetate and carbazole. The structure was confirmed by ^1H NMR and IR. Its electron structure was investigated primarily by UV-Vis. Compared with acylpyrazolone or carbazole group, 6 exhibits special electron structure.
