INOR 213 |
| Ethylene, the plant ripening hormone, is responsible for the annual loss of millions of dollars in produce due to spoilage during shipment and storage. The ability to sense and control ethylene would improve upon existing methods to prevent rotting, but commercial sensors are prohibitively expensive. We are investigating possible luminescent sensors that use a Ag(I) ion to interact with both ethylene and a fluoroionophore to mediate the sensing event. When ethylene reversibly binds to a Ag(I) ion, it alters how Ag(I) interacts with the ligated fluoroionophore resulting in an emission intensity change. The fluoroionophores tested are anthracene derivatives, substituted at the 9 position with an aliphatic tether including N and S heteroatoms as amines, amides, and thioethers. Data from fluorescence studies of Ag(I)-bound fluoroionophores exposed to ethylene will be presented. The effect of the number of heteroatoms binding to Ag(I) and the basicity of the nitrogen will also be discussed. |
