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.

用于食品腐败标记剂的吡喃盐快速视觉检测胺
胺在生物界无处不在，但在自然界中却是有毒有害的。检测从变质的海鲜、肉类或乳制品中释放的生物胺是维持这些包装食品的质量和安全性的一项重要任务。为此，我们在此报告了能够通过荧光颜色或强度的快速变化来感知各种胺的吡喃盐。在分子水平上，这种荧光的变化源于吡啶或具有不同光学性质的类似产物的形成。pyrylium盐能够有效地检测固态和溶液状态的胺蒸气或胺溶液，从而展示了多相传感平台。利用优异的传感特性，我们已将我们的 pyrylium 化合物用作鱼、肉或奶酪等食品的腐败指示剂，这些指示剂依赖于感知这些变质食品中释放的生物胺并提供光学响应。在室温（~33°C）下，在包装后 4-18 小时内观察到可见光和发光颜色的显着变化。考虑到对生物胺的快速响应，这些分子传感器具有巨大的潜力，可用于食品包装行业、医疗诊断或其他传感设备。
