摘要： 合成了八-4-(四氢糠氧基)酞菁钕(Ⅲ)(A)、八-4-(β-萘氧基)酞菁钕(Ⅲ)(B)、八-4-(2,4-二叔戊基苯氧基)酞菁钕(Ⅲ)(C)和八-4-(2,4-二叔戊基苯氧基)酞菁镨(Ⅲ)(D)4种新的稀土(Nd、Pr)(Ⅲ)双酞菁衍生物,经元素分析、红外光谱、核磁共振谱表征。紫外可见光谱表明,它们在氯仿(10-6mol/L)溶液中以单分子形式存在。热重分析证明配合物的热稳定性：B>C～D>A.4种配合物成膜性好,Z型沉积形成的单层LB膜材料对氨气有响应,特别是八-4-(四氢糠氧基)酞菁钕(Ⅲ)的膜材料对氨气很敏感,可与铜酞菁LB膜气敏性相比。

Abstract: In this paper, Nd(Ⅲ) -octa-4-(tetrahydrofurfuroxy) phthalocyanine (A), Nd(Ⅲ)-octa-4-(β-naphthoxy)phthalocyanine (B), Nd(Ⅲ)-octa-4-(2, 4-di-t-pentylphenoxy) phthalocyanine (C) and Pr(Ⅲ)-octa-4-(2, 4-di-t-pentylphenoxy) phthalocyanine(D) were synthesized and characterized by elementary analysis, IR, 1H NMR, UV-Vis spectra. It is indicated that most of them were monomeric molecules in CHCl3 solution. The thermostability order was B >C～D>A. Four kinds of compounds have good film-forming ability.The LBfilms of ADdeposited on gold comb electrode by the LBtechniques according to the Z-type. The gassensibility of LBfilms was determined. The results showed that the films have good sensibility and selectivity for the vapor of NH3. And then the Nd(Ⅲ)-octa-4-(tetrahydrofurfuroxy) phthalocyanine(A) has the best gas-sensibility for the vapor of NH3 comparable with copper (Ⅱ) phthalocyanine.
