: 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).

葫芦[n]脲半导体界面的功能化

：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。由于它们对带正电或阳离子化合物的高结合亲和力，它们通常被用作超分子化学应用中的有效主体分子。本综述研究了 CB[n] 固定在半导体界面上生产电化学传感器的应用。薄膜电极制剂生产的关键是 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；然而，CB[7]已成功应用于各种电化学传感器的生产。此外，我们引入了有效溶解的 CB[7] 的简单滴铸法，作为一种简单而有效的方法来生产 CB[7] 修饰的电化学传感器，用于敏感报告浓度范围为 3.33×10-9 至 3.33×10-9 的水溶液中的多巴胺。 1.16×10-8 M，灵敏度为 0.315 µA/M，(n=3)。
