摘要
"催化"是广泛的应用于合成化学中的概念,将其应用到分子组装的研究过程,提出用于调控和加速分子组装的过程,即"催组装",具有非常重要的研究意义。本文中我们利用有机酸和金属离子催化TCTPA形成荧光微米管。将有机酸和金属离子加入到TCTPA的盐溶液中,向其混合溶液中加入盐酸,降低体系的pH值,可以得到结构规则的TCTPA的微米管。通过有机元素分析、~1H NMR和EDS,我们证明了形成的微米管中,只有TCTPA本身,并没有有机酸和金属离子的存在。因此在本体系中,有机酸和金属离子起到了一个催化剂的作用,从而实现了TCTPA的催组装。通过该工作,我们希望可以了解催组装的一些本质工作,通过分子组装来实现高效率和高选择性的创造新的物质。
The concept of catalysis,which is widely used in chemical synthesis,could be extended to molecular assembly.Herein we suggest that the term "cassemblysis" be used when referring to increased rates and control during assembly.In this work,we report that the case of organic acid and metal ions catalyzed self-assembly of the TCTPA into microtubes.Adding organic acid and metal ions to the TCTPA salt solutions,and then reducing the pH value of system using HCl,the microtubes can be formed.Organic elemental analysis,H NMR and EDS suggest that the organic acid and metal ions were not involved into the microtubes.Organic acid and metal ions,played the role of a catalyst in the formation of TCTPA microtubes.Through this work,we hope that we can understand the nature of cassemblysis,using molecular assembly to achieve high efficiency and high selectivity to create new material.
