Amines are ubiquitous in biological world, but are toxic and
harmful in nature. Detection of biogenic amines that are released from spoiled
seafood, meat, or dairy products is an important task to maintain the quality
and safety of these packaged foods. To this endeavor, herein we report
pyrylium salts that are capable of sensing various amines by rapid change of
fluorescence color or intensity. In molecular level, this change of fluorescence
is rooted to the formation of pyridine or analogous product that have distinct
optical property. The pyrylium salts are capable of efficiently sensing amine
vapors or amine solutions both in solid state and in solution state and thus
demonstrating a multiphase sensing platform. Utilizing the excellent sensing
property, we have employed our pyrylium compounds as spoilage indicator
for food products such as fish, meat or cheese which relies on sensing biogenic
amines released from these spoiled foods and provide optical response.
Prominent change in visible and luminescence color was observed within 4?
18 h of packaging at room temperature (?33 °C). Considering the rapid response for biogenic amines, these molecular sensors have great potential to be utilized for food packaging industry, medical diagnostics, or other sensory devices.
