在二甲基甲酰胺(DMF) 中合成了Fe ( Ⅲ) 与一分子2 ,2′2 联吡啶- 1 ,1′2 二氧化物(bipyO2 ) 的新化合物[ Fe (bipyO2) Cl2 ]Cl·1/ 6 bipyO2 。用元素分析、摩尔电导、红外光谱和紫外光谱等方法测定了它的组成。用该配合物制作的传感器对氨气有极高的敏感性和选择性。可用于氨气泄漏报警和对环境中氨气的实时监测。
关键词:传感器; 2 ,22联吡啶- 1 ,1′2 二氧化物; 配合物; 合成; 三氯化铁
Abstract : The coordination compound of Fe( Ⅲ) with 2 ,22bipyridine - 1 ,12dioxide was synthesized , It was char2 acterized by elemental analysis , IR ,UV and molar conductivity. The gas sensitive property was studied ,the re2 sults indicated that the composition of the coordination compound is [ Fe(bipyO2) Cl2 ]Cl·1/ 6 bipyO2 . The sensor manufactured by coordination compound has very high sensitivity and selectivity to ammonia. It could be used in ammonia leak2alarm and in environment realtime supervising ammonia.
Key words :sensor ;2 ,2′2 bipyridine - 1 ,1′2 dioxide ;complex ;synthesis ;FeCl3
