Four 14-membered azamacrocycles 2a−d, each containing a pyridine moiety and three acetic and/or propionic acid pendent arms, were prepared from regioselectively functionalised polyamines. The stability constants of the lanthanide complexes (La, Pr, Nd, Eu, Gd, Tb, Er, Yb, Lu) formed with the triacetic acid compound 2a were determined by spectroscopic methods (luminescence and/or UV/Vis spectroscopy)
四个 14 元氮杂大环 2a-d,每个都包含一个吡啶部分和三个乙酸和/或丙酸悬垂臂,由区域选择性功能化的多胺制备。与三乙酸化合物2a形成的镧系元素络合物(La、Pr、Nd、Eu、Gd、Tb、Er、Yb、Lu)的稳定性常数通过光谱方法(发光和/或UV/Vis光谱)确定。还评估了与三乙酸衍生物 2a 形成的发光 EuIII 和 TbIII 复合物的其他特性。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
