设计并实施了一种前所未有的分子泵送盒,用于构建分子链,即径向 [ n ] 链烷。该机制在模型[2]伪轮烷上得到充分证实,并采用新颖的剪切后泵送策略制备了一系列[ n ]链烷(n = 2-5)。一对[3]链烷非对映异构体依次与两个不同的轮子螺纹连接也得到了完成。利用分子泵浦构建分子项链的成功为复杂分子结构提供了新的见解,并扩大了分子机器在合成中的应用。

The metalation of all positions of the benzo[c][1,2,5]thiadiazole scaffold using LiCl-solubilized TMP-bases is demonstrated on various substrates. Thus, unsymmetrically substituted benzothiadiazole derivatives and a new fused thiadiazoloindazole have been prepared.

derivatives due to an intramolecular charge transfer (ICT) in the excited state. The studied derivatives present potential optical application since combine large extinction coefficient for absorption, largeStokesshift and high fluorescence emission. Additionally, these dyes exhibit binding selectivity to Ni+2 among a series of cations in CH3CN solution.
Abstract Two nonsymmetrical π-extended 2,1,3-benzothiadiazoles (BTDs) bearing a 4-pyridyl moiety (BTD-4pyr and BTD-Et4pyr) were synthesized by sequential cross coupling reactions. The structural difference between the two dyes is the presence of a triple bond between the BTD core and the 4-pyridyl moiety in BTD-Et4pyr. The compounds architecture is similar to previously described selective mitochondrial

absorption in blue region and emission ranging from 531 to 560 nm with positive solvatochromism. Lippert Mattaga plots indicated a substantial effect of solvent polarity over the emission profile. As the fluorescence of the compound 4 was more sensitive to changes in the environment, this compound was evaluated as a probe to chemosensing etanol/water percentage in hydroalcoholic solutions. Good linearity
