在这项研究中,我们报告了第一个基于葫芦[ n ] uril(CB n)宿主的超分子指示剂置换试验(IDA),该宿主可在血清中运行。通过详细的数学模拟,得出了竞争性结合介质中主客体化学感应的合理设计原则。结果表明,目前已知的CB n基的化学感觉合奏不适用于竞争激烈的矩阵,例如血清。相反,模拟表明葫芦丝[8] uril(CB8)和超高亲和力染料的组合将是用于检测血清中阿尔茨海默氏病美金刚的有前途的IDA报告物对。因此,针对宿主CB8的新型[2.2]对环环烷衍生的指示剂被开发出来,它具有超分子宿主-客体化学中已知的最高宿主-客体亲和力之一(在水中K a > 10 12 M -1),并提供较大的斯托克斯位移(最大200 nm)。然后测试了新的IDA,以检测在生理相关的亚微摩尔浓度至低微摩尔浓度范围内的血清中的美金刚。

Pyridyl‐substituted [2.2]paracyclophanes build a multifunctional structural motif that is useful in material chemistry, catalysis and for luminescent structures. Nonetheless, there is still a lack of general methods for the synthesis of these structures tolerating easily accessible bromides as well as different isomeric pyridyl groups. Hence the coupling of functionalized [2.2]paracyclophanes with various substituted

chiral pyridyl[2.2]paracyclophanes were prepared by the palladium‐catalyzed desulfinative cross‐coupling of bromo[2.2]paracyclophanes and pyridine sulfinate salts. Pyridine‐substituted [2.2]paracyclophanes are useful building blocks in the preparation of catalysts, functionalized materials, and luminescent molecules. Yet the synthesis of many pyridine‐substituted [2.2]paracyclophanes is more challenging
Synthesis of Mono‐, Di‐, Tri‐, and Tetra‐cationic Pyridinium and Vinylpyridinium Modified [2.2]Paracyclophanes: Modular Receptors for Supramolecular Systems
Modular Scaffolds for Supramolecular Systems: In this report, a new series of mono-, di-, tri-, and tetra-cationic pyridinium and vinylpyridinium modified [2.2]paracyclophanes (PCPs) is described. On N-methylation, the 3D PCPs bearing (cationic) pyridyl and vinylpyridinium functionalities have been demonstrated as efficient molecular receptors for application in supramolecular systems. The PCPs on
