摘要:
以罗丹明B (RhB)、水合肼、苯甲醛为原料,通过两步反应合成了一种新型罗丹明B类荧光探针RhB-P,并利用傅里叶红外变换光谱与核磁共振氢谱对RhB-P的分子结构进行表征。紫外-可见光谱和荧光光谱表明:在V(乙腈)∶V(水)=1∶1溶液中,RhB-P对Fe3+具有良好的选择性,溶液可从无色转变至粉色。荧光滴定实验以及Job’s 实验结果表明:络合物中n(RhB-P)∶n(Fe3+)=1∶1,且络合物的荧光强度在c(Fe3+)为0.1 μmol/L~20 μmol/L区间范围内,与其呈正线性关系,检出限为0.193 μmol/L。
Abstract:
A novel Rhodamine B-derived fluorescent probe (RhB-P) was synthesized through two steps with Rhodamine B,hydrazine hydrate and benzaldehyde as the raw materials. Fourier-transform infrared spectroscopy and 1H-nuclear magnetic resonance spectroscopy were utilized to investigate the chemical structure of RhB-P. UV-vis and fluorescence spectroscopy demonstrated that the probe RhB-P recognized Fe3+ with high selectivity in the V(acetonitrile)∶V(H2O) =1∶1 solvent, and the colorless solution turned into the pink one. Meanwhile,the fluorescence titration and Job’s plot revealed that RhB-P combined with Fe3+ into a stable chelate complex of n(RhB-P)∶n(Fe3+)=1∶1,and the fluorescent intensity of the complex solution displayed a positive linear relationship with Fe3+ concentration in the range of 0.1 μmol/L to 20 μmol/L with 0.193 μmol/L of detection limit.
