In this work, we developed a fluorescence probe HCPM with AIE effect. The probe HCPM in solid state showed obvious fluorescence colormetric response from orange-red to green for cadaverine vapor with high selectivity and could quantitative detect cadaverine vapor and a visual detection platform was constructed by combining it with a smartphone. Also, the probe HCPM exhibited significant fluorescence colormetric responses for 12 BAs and could detect the different concentrations of cadaverine in EtOH/HO (1/9, v/v, pH = 7.4) solution. Moreover, the probe HCPM was loaded on the test paper and silica gel plate as sensing label, which could be used to visual detect the freshness of pork and shrimp.
