  Supramolecular Adsorption of Alkaloids by Metallosalphen Complexes

  摘要：

  Mono and bis-zinc(II)-centered salphen derivatives 1-5 are presented as efficient adsorption materials for pyridine-based alkaloid derivatives. The different alkaloid assemblies were studied by UV-vis and NMR spectroscopy, and high binding constants (K, similar to 10(5)) were additionally determined for the supramolecular complexes based on nicotine. X-ray analyses furthermore revealed, together with spectroscopic. solution data, a preferential positioning of the nicotine guest(s). Upon binding to bis-Zn-II-bis-salphen complexes, the dinicotine assembly provokes a colorimetric change that may be useful for colorimetric analyses. The adsorption/desorption process of nicotine was studied using a polymeric bis-Zn(salphen) complex (5) and showed a recycling potential of this type of complexes in the binding of alkaloid compounds.

  structures provoked by unusual oligomeric (Zn-O)(n) coordination motifs within the assembly. This coordination mode is strikingly different when compared with mononuclear Zn(salphen) analogues that form dimeric structures having a typical Zn(2)O(2) central unit. The high stability of the multinuclear structure therefore holds great promise for the development of stable self-assembled monolayers with potential

  扫描隧道显微镜、竞争性紫外-可见光和荧光滴定、动态光散射和透射电子显微镜证明了双锌 (salphen) 结构在溶液和固-液界面中都显示出极强的自组装。对 Zn(2) 复合物的密度泛函理论分析合理化了由组装中不寻常的低聚 (Zn-O)(n) 配位基序引起的自组装结构的非常高的稳定性。与形成具有典型 Zn(2)O(2) 中心单元的二聚结构的单核 Zn(salphen) 类似物相比，这种协调模式是截然不同的。因此，多核结构的高稳定性为开发具有新光电材料潜力的稳定自组装单层提供了广阔的前景。
