A series of crown ethers carrying an anthracene group with nitrogen–sulfur donor atom, which differ in having three, four and five sulfur atoms in the macrocycle was designed and synthesized by the reaction of the corresponding macrocyclic compound and 9-chloromethyl-anthracene. The influence of metal cations such as Al3+, Zn2+, Fe2+, Fe3+, Co2+, Ni2+, Mn2+, Cu2+, Cd2+, Hg2+ and Pb2+ on the spectroscopic
通过相应的大环化合物与9-氯甲基蒽的反应,设计合成了一系列带有蒽基的氮-硫给体原子的冠醚,它们在大环中具有三个,四个和五个硫原子。Al 3+,Zn 2 +,Fe 2 +,Fe 3+,Co 2 +,Ni 2 +,Mn 2 +,Cu 2 +,Cd 2 +,Hg 2+和Pb 2+等金属阳离子的影响在乙腈-二氯甲烷(1:1)中通过吸收和发射光谱法研究了配体的光谱性质。吸收光谱显示分光光度滴定法中的Al 3+,Zn 2 +,Fe 2 +,Fe 3+,Cu 2 +,Hg 2+和Pb 2+的等吸收点,其结果揭示了该化合物的络合物组成和络合物的稳定常数。具有这些阳离子的新型配体。单氮杂蒽醌冠醚显示出对Al 3+的灵敏度,线性范围和检测极限分别为2.6×10 -6 M–2.6×10 -5 M和8.1×10 -7 M分别。
