Abstract

: Cucurbiturils are a class of macrocyclic compounds with highly polar carbonyl portals and a hydrophobic cavity. They are usually utilized as efficient host molecules in supramolecular chemistry applications due to their high binding affinity for positively charged or cationic compounds. This review investigates the application of CB[n] immobilization at semi-conductive interfaces to produce electrochemical sensors. Critical to the production of thin film electrode preparations is the solubility of the CB[n] to produce homogeneous thin films when deposited. The solubility of CB[n] molecules in organic and inorganic solvents is limited; however, CB[7] has been applied successfully in the production of a wide range of electrochemical sensors. Furthermore, we introduce simple drop-casting of efficiently solubilized CB[7] as a simple yet effective method for producing CB[7] modified electrochemical sensors for the sensitive reporting of dopamine in aqueous solutions in the concentration range of 3.33×10-9 to 1.16×10-8 M with a sensitivity of 0.315 µA/M, (n=3).
用葫芦[n]脲使半导电界面功能化
:葫芦脲是一类具有高极性羰基门户和疏水空腔的大环化合物。由于它们与带正电荷或阳离子的化合物具有很高的结合亲和力,因此在超分子化学应用中通常被用作高效的宿主分子。本综述探讨了如何将 CB[n] 固定在半导电界面上以生产电化学传感器。薄膜电极制备的关键是 CB[n] 的溶解度,以便在沉积时产生均匀的薄膜。CB[n] 分子在有机和无机溶剂中的溶解度有限,但 CB[7] 已成功应用于生产各种电化学传感器。此外,我们还介绍了一种简单而有效的方法,即利用高效溶解的 CB[7] 进行简单的液滴浇铸,来生产 CB[7] 改性电化学传感器,用于灵敏地报告水溶液中多巴胺的浓度,浓度范围为 3.33×10-9 至 1.16×10-8M,灵敏度为 0.315 µA/M(n=3)。
