摘要
以5-甲酰基-3,4-二甲基吡咯-2-羧酸乙酯和罗丹明B酰肼为原料,合成了一种"Off-On"型罗丹明衍生物Cu^2+荧光探针R1.探针R1对Cu^2+识别具有高选择性和高灵敏度,其检出限(LOD)为0.201μmol·L^-1,此外探针R1与Cu^2+作用后颜色从无色变为粉红色,可以实现Cu^2+的"裸眼检测".探针R1成功用于实际水样中Cu^2+的检测.
Ethyl 5-formyl-3,4-dimethyl-pyrrole-2-carboxylate and rhodamine B hydrazide were used to synthesize a rhodamine derivative R1.Notably,the as-synthesized R1 displayed great sensitivity and selectivity,which was utilized to be an off-on fluorescence probe for Cu^2+detection in mediums that contained water.Besides,the Cu^2+ions limit of detection(LOD)was 0.201μmol·L^-1,and R1 was able to sense Cu^2+by"naked-eye"according to the change in color to pink from colorless.In addition,Cu^2+detection was assessed within the actual water samples for testing the probe actual application.
