A crystalline 14-metal Zn-Nd cluster [ZnNdL(OAc)(O)(NO)(OCH)] (1) was constructed using a flexible Schiff base ligand with long-chain (CH)O(CH)O(CH) backbone. 1 exhibits a nanoscale rectangular structure (10 × 14 × 18 Å). Besides the visible ligand-centered emission, 1 displays typical NIR luminescence of Nd. Interestingly, 1 shows both a ligand-centered and lanthanide fluorescence response towards metal ions, especially to K and Co at the ppm level.
使用具有长链(CH)O(CH)O(CH)主链的柔性席夫碱配体构建了一种晶体状的14金属锌-钕簇合物[ZnNdL(OAc)(O)(NO)(OCH)] (1)。1呈现出纳米级的矩形结构(10×14×18 Å)。除了以配体为中心的可见发射外，1还显示出钕典型的近红外发光。有趣的是，1对金属离子，尤其是对ppm级别的钾和钴，表现出以配体为中心和镧系元素的荧光响应。
