A novel fluorescent probe of alkyne compounds for putrescine detection based on click reaction.

ABSTRACT: Putrescine is a toxic biogenic amine produced in the process of food spoilage, and a high concentration of biogenic amines in foods will cause health problems such as abnormal blood pressure, headaches and tachycardia asthma/worsening asthma. The detection of putrescine is necessary. However, traditional putrescine detection requires specialized instruments and complex operations. To detect putrescine quickly, sensitively and accurately, we designed and successfully prepared a fluorescent probe (DPY) with active alkynyl groups. DPY takes p-dimethoxybenzene as the raw material, adding a highly active alkyne group. It is stable in experimental pH (∼7) because the UV-vis absorption and fluorescence emission spectra in pH = 3-12 have little change. The fluorescence intensity of DPY decr
