芳呋喃吡唑啉的合成和波谱研究

Studies on the Synthesis and Spectra of Arylfurylpyrazolines

合成了14种新的1-苯基-5-对二甲胺基苯基-3-芳呋喃基及3-芳呋喃乙烯基吡唑啉衍生物。测定了它们的紫外、红外、核磁、质谱和荧光光谱。对合成反应过程中缩合环化方向进行了讨论。初步考察了所得吡唑啉的光导电性和电致变色性质。

In this paper, fourteen new 1-pnenyl-5-(p-dimethylaminophenyl)-3-arylfuryl and -3-aryl-furylethenylpyrazoline derivatives were synthesized. The IR, UV/Vis, FL, MS, 1H NMR spectra were determined. Some discussion was made on the direction of cyclization in the reaction of substituted pentadienone with phenylhydrazine. The photoconductivity and electrochromic property of pyrazo-lines obtained were also studied.
