设计合成了含噻唑和腙结构的香豆素类钴离子荧光探针分子CCo,其结构用1HNMR和13CNMR进行了表征,考察了其光谱性能和电化学性能,并对其结构进行了拟合计算研究。CCo在常见金属离子(Cd2+、Co2+、Na+、Mn2+、Fe3+、Pb2+、Hg2+、Cu2+、Zn2+、Cu+、K+、Mg2+、Ag+、Ni2+、Cr3+)中能够选择性地识别Co2+。滴加Co2+后探针吸收光谱红移60 nm,荧光光谱蓝移75 nm。探针分子溶液在三电极系统及四丁基高氯酸胺作电解质下能用于Hg2+的检测。通过拟合计算进一步验证了探针吸收光谱峰值与实验值一致。
The coumarin-based cobalt ion fluorescent probe molecule CCo containing thiazole and hydrazone structures was designed and synthesized. Its structure was characterized by 1HNMR and 13CNMR. The spectroscopic and electrochemical properties of the coumarin-like cobalt ion probe were calculated and its structure was calculated. the study. CCo can selectively recognize Co2 + in common metal ions (Cd2 +, Co2 +, Na +, Mn2 +, Fe3 +, Pb2 +, Hg2 +, Cu2 +, Zn2 +, Cu +, K +, Mg2 +, Ag +, Ni2 +, Cr3 +). After the addition of Co2 +, the absorption spectrum of the probe was red-shifted by 60 nm and the fluorescence spectrum was blue-shifted by 75 nm. The probe molecule solution can be used for the detection of Hg2 + under a three-electrode system and tetrabutyl ammonium perchlorate as electrolyte. The peak of the absorption spectrum of the probe was further verified by fitting calculation.
