Porphyrin complexes become ideal models for the study of porphyrin sensors because of excellent properties of light sensitivity,chemical stability,easy modification,especially for that very a little of fluctuate can be monitored and be determinated either in the spectroscopy methods of UV,IR,fluorescence,phosphorescence and Laman,or in elctroanalytical method conveniently.New research progress of porphyrin oxygen sensor,porphyrin CO2sensor,porphyrin chlorid sensor,porphyrin biosensor and other porphyrin sensors is introduced and the development of porphyrin sensors is prospected.
