摘要: Abstract An amphiphilic metalloporphyrin, cobalt (II) 5, 10, 15-tri( p -octadecyloxyphenyl)-20-( -hydroxyphenyl)porphyrin (CoPPC 18 ) was synthesized and characterized. The molecules of CoPPC alone form moderate stable monolayer at the air-water interface a clear phase transition observed in surface pressure-area isotherm. optical Mach-Zhender interferometer prepared as novel sensor element incorporating with Langmuir-Blodgett films. preliminary result indicates that is sensitive reversible on exposure to NO 2 gas room temperature.
