18-dibenzo-cyclooctadecane-6,14-dione ( TTD ) and 7,10,13-triaza-1-sulfoxo-4,16-dioxa-20,24-dimethyl-2,3;17,18-dibenzo-cyclooctadecane-6,14-dione ( TSD ) macrocycles with Ag+, Cd2+, Cu2+, Pb2+, Sr2+, Tl+, and Zn2+ ions have been studied in ethanol and methanol solutions at 25°C. The complexes formed between macrocycles ( TTD ) and ( TSD ) with these metals cations had a stiochiometry of 1:1 and 1:2, respectively.
7,10,13-triaza-1-thia-4,16-dioxa-20,24-dimethyl-2,3;17,18-dibenzo-cyclooctadecane-6,14-dione (TTD)与7之间的络合反应,10,13-triaza-1-sulfoxo-4,16-dioxa-20,24-dimethyl-2,3;17,18-dibenzo-cyclooctadecane-6,14-dione (TSD) 大环化合物与 Ag+, Cd2+, Cu2+ 、Pb2+、Sr2+、Tl+ 和 Zn2+ 离子已在 25°C 的乙醇和甲醇溶液中进行了研究。大环化合物 (TTD) 和 (TSD) 与这些金属阳离子形成的配合物的化学计量比分别为 1:1 和 1:2。测定所得配合物的稳定性常数,发现其以 Cu2+ > Zn2+ > Ag+ > Tl+ > Cd2+ > Pb2+ > Sr2+ 与大环 (
