摘要： 四-(4-N,N-二甲基氨基苯基)卟啉(TDMAPP)与溴代正十六烷反应得到溴化四-(4-N,N,N-二甲基,十六烷基氨基苯基)卟啉(TDMHAPPBr),并制得其钴的配合物,两者均具有良好的成膜性。电子吸收光谱表明LB膜与成膜前固体物分子排列规整性不同。钴配合物对氨气有较好的敏感性和良好的选择性,其响应和恢复时间都较短。

Abstract: Tetra-(4-N,N-dimethylaminophenyl)porphyrin(TDMAPP) reacts with n-C16H33Br to yield the product tetra(4-N,N,N-dimethyl hexadecylaminophenyl)porphyrin bromide (TDMHAPPBr).Its cobalt complex was also prepared.Both porphyrin and its complex have good film-forming properties.The UV-visible spectra of the LBfilms and solid state show that the two states have different styles in the molecular interactions.The gas sensitivity study of the cobalt complex indicates that the complex is sensitive to NH3 and has a good selectivity.The response and recovery times are short.

Key words: Porphyrin, LB films, Gas sensitivity
