The binding of Na+, K+ and Mg2+ to benzo-15-crown-5 and aza-15-crown-5 directly-linked ferrocenes results in shifts of the ferrocene oxidation wave to more positive potentials. The magnitude of these anodic shifts is related to the charge/radius ratio of the cationic guest. The results of an X-ray diffraction study of the structure of a ferrocene benzo-15-crown-5 sodium complex are also reported.
Na +,K +和Mg 2+与直接连接的苯并15-15-crown-5和aza-15-crown-5的二茂铁结合导致二茂铁的氧化波向更正的电位移动。这些阳极位移的大小与阳离子客体的电荷/半径比有关。还报道了二茂铁苯并15-15冠5钠配合物的X射线衍射研究结果。
