  Amine-Promoted β-Elimination of a β-Aryloxy Aldehyde for Fluorogenic Chemodosimeters

  摘要：

  We previously reported a fluorescent chemodosimeter for ozone. The beta-elimination step after the ozonolysis of the chemodosimeter was too slow to be practical for real-time monitoring of ozone. We examined primary, secondary, and tertiary amines at various pHs. It was found that pyrrolidine in pH 9 buffer could accelerate the elimination to generate a fluorescence signal. The elimination step is now sufficiently rapid to monitor ozone exposure in real time. We also discovered that azetidine was distinctly effective for the same elimination reaction in a pH 6 buffer.

  A selective, fluorescent “turn-on” probe and method for the detection of ozone in biological and atmospheric samples, wherein the method of detecting ozone in a sample comprises the steps of (1) contacting the sample with a fluorophore capable of undergoing allylic ether or allylic ester cleavage and (2) detecting fluorescence in the sample.
