  摘要：

  合成了将大三环聚醚和两个二苄基铵离子结合在一起的自互补单体1，并研究了其通过主客体相互作用自组装为超分子聚合物网络的过程。为了进行比较研究，还制备了两个模型分子2和3。发现模型分子2和二苄基铵离子4在溶液中和在固态下形成1：2的络合物，这为研究单体1的组装行为提供了模型系统。因此，CD 3中1的1 H NMR光谱CN显示出与模型系统相似的质子信号，表明1个自组装成超分子聚合物网络。MALDI-TOF MS光谱，粘度测定和动态光散射（DLS）实验进一步证明了超分子聚合物的形成。此外，发现超分子聚合物的分解和重整可以通过使用三乙胺和三氟乙酸进行化学控制。有趣的是，超分子聚合物在CD 3 CN和1：1（v / v）CDCl 3 / CD 3中均形成有机凝胶。还发现了CN以及可逆的热和pH诱导的凝胶-溶胶转变。提出的工作将为构建具有特定结构和性质的超分子聚合物提供新的策略。

  Copper-aluminium hydrotalcite (CuAl-HT)/K2CO3 has been employed in the activation of various benzyl alcohols with benzylamines to afford the corresponding amines in good to high yields. Experimentation showed that the reaction takes place through sequential transformations: the oxidation of alcohols into carbonyl compounds, imine formation between amines and carbonyl compounds, and then reduction ofimines

  A Cp*Ir(III) complex (1) bearing a proton-responsive hydroxy unit on an annulated imidazo[1,2-a][1,8]naphthyridine based mesoionic carbene scaffold was synthesized by two different synthetic routes. The molecular structure of 1 revealed an anionic lactam form of the ligand. The acid–base equilibrium between the lactam-lactim tautomers on the ligand scaffold was examined by 1H NMR and UV–vis spectra
