杯芳烃的配位化学Ⅶ.水溶性杯[8]芳烃与过渡元素配合物的热力学研究

COORDINATION CHEMISTRY OF CALIXARENES Ⅶ.STUDY ON METAL COMPLEXES OF WATER SOLUBLE CALIXARENES WITH Sc 3+ 、Y 3+ 、La 3+

本文首次报道了八对磺酸钠八羟基羰基甲氧基杯［８］芳烃酸离解常数的测定结果，还以ｐＨ滴定法对该试剂与过渡元素的各种配合物进行系统研究，发现此配体能形成ＭＨｎＬ（ｎ＝１－７）型配合物。

A pH potentiometric titration method has been used to determine the acid dissociation constants of octasulfonato octakis(carboxy) calixarene and cumulative stability constants complexes of octasulfonato octakis(carboxy) calixarene with transition element at 30℃, and ionic strength I =0.1. It has been found that ligand can from such coordination compounds as MHnL(n=1 7) with transition element. Which has not been reported up to now.
