Proper shielding: Encapsulatedoligothiophenes for the investigation of single‐molecule conductance are described. UV/Vis/NIR measurements of the oxidized species show the absence of intermolecular interactions between the conjugated backbones. The conductance of a single‐molecule junction was measured by modified STM techniques (see picture), and the decay constant β was determined to be 1.9 nm−1
适当的屏蔽:描述了用于研究单分子电导的封装的寡聚噻吩。氧化物种的UV / Vis / NIR测量表明,共轭骨架之间没有分子间相互作用。单分子结的电导率通过改进的STM技术测量(参见图片),衰减常数β确定为1.9 nm -1。SMU =源计量单位。

Résumé A simple, green, and environmentally benign protocol for squaric acid (5 mg) catalyst conjugate addition of aromatic amines and thiols to unsaturated carbonyl compounds in water in good to excellent yields is developed. The advantages of low sensitivity toward moisture and oxygen, high tolerance of different functional groups, green reaction media and efficient recyclability make this organocatalyst suitable for both laboratory and industrial scale synthesis of β-substituted carbonyls under very mild conditions.
