利用简单反应首次合成功能取代的开链二氧四胺配体，此配体含有苯环取代羟甲基侧链，此反应原料易得、产率高．该配体经过元素分析、核磁和红外光谱表征．在（２５．０±０．１）℃，Ｉ＝ ０．１ｍ ｏｌ·ｄｍ － ３ ＮａＮＯ３ 条件下，用ｐＨ法测定了配体的质子化常数、与过渡金属离子铜（Ⅱ）在溶液中的二元配合物稳定常数，并从滴定数据讨论了物种的可能构型．
Using simple reaction for the first time synthesis of functional substituted open chain diaminetetraamine ligand, the ligand containing a benzene ring instead of hydroxymethyl side chain, the reaction raw materials easily available, high yield. The ligand is characterized by elemental analysis, nuclear magnetic and infrared spectroscopy. Under the conditions of (25.0 ± 0.1) ℃, I = 0.1mol · dm - 3 NaNO3, the protonation constants of the ligand were determined by the pH method, The stability constants of binary complexes and the possible conformations of the species are discussed from the titration data.
