本文以六氟丙烯二聚体和N，N-二甲基丙二胺为主要原料合成了两种含氟中间体叔胺——N，N-二甲基-N'-(2-三氟甲基-1-五氟乙基)全氟丙烯基丙二胺和N，N-二甲基-N'-(2-三氟甲基-1-五氟乙基)全氟烯丙基丙二胺，用薄层色谱和柱色谱等方法对产品进行分离提纯，并运用红外光谱和核磁共振等分析手段对其结构进行了表征。

The results indicated that the composite films exhibited much improved gas sensing performance.The phthalocyanine and its a-Fe2O3 embedded nano-particulate LB filmswere prepared by Langmuir-Blodgett technique. The films were characterized by AFM, UV-Vis and FT-IR spectra. The results indicated that the embedded LB films were composed of a-Fe2O3 nanoparticles and isopropoxyphthalocyanine molecules. The gas sensitivity of such prepared composite LB films was greatly improved. The film could detect 5ppm of propyl alcohol at room temperature. The composite films could be considered as gas-sensors for alcohols.

利用LB技术制各了异丙氧基酞菁铜LB膜和酞菁铜包埋球形α-Fe_2O_3纳米粒子的杂化LB薄膜，对其AFM、紫外和红外光谱的研究表明，利用LB技术可以实现酞菁与α-Fe_2O_3纳米粒子的有序组装，而且杂化薄膜对醇类气体的灵敏度有较大幅度提高，如对浓度为5ppm正丙醇的灵敏度为3.85，因此，杂化薄膜可以作为室温下醇类气体传感器进行开发研究。
