溴化四-(4-N,N,N-二甲基,正庚烷基氨基苯基)卟啉钴的合成,L-B膜及其气敏、湿敏特性

SYNTHESIS, LB FILMS, GAS AND HOMID SENSOR OF COBALT TETRA-(4-N, N, N- DIMETHYLHEPTYLAMINOPHENYL) PORPHYRIN BROMIDE

卟啉和酞菁是一类大环共轭化合物,由于其结构和性能以及在生命科学中所起的作用,使得用L-B膜技术研究其结构和功能越来越引起人们的重视.自从Jones等发现原卟啉L-B膜具有较好的光导性以来,卟啉L-B膜的电导性和气体敏感特性相继有人进行过研究。

Amphipathic porphyrin tetra-(4-N, N, N-dimethylheptylaminophenyl) porphyrin bromide and its cobalt complex were synthesized. The π-A isotherm and film-forming property of the cobalt complex indicate that it can form good LB films. The LB films device of the complex is sensitive to NH3 and homid, and has short responding and recovery times.
