摘要
We report herein the synthesis and spectroscopic study of the first spiropyrandinolines that function as sensors for metal ions in the parts per billion range. These systems operate by either photochemically or chemically induced reversible formation of merocyanine metal ion complexes. The application of this novel photodynamic sensing material to sensor technology is discussed.
