摘要:

利用 1H和 13C NMR, IR, UV, SEM对合成的4种C型和S型拓扑异构体进行了结构表征和分析, 发现对于不同拓扑结构的C型和S型分子可以通过 1H NMR来鉴别, 而对于相同拓扑结构的S型cis(SC)和trans(ST)分子,  C型 cis(CC)和trans(CT)分子则要结合 13C NMR来鉴别. 四种拓扑异构体的IR, UV, 波谱性质以及SEM图象没有显著的差异.

Abstract:

With the development of the supramolecular chemistry, a type of novel stereoisomers with the same chemical formula and connectivity but different folding shapes has been found. These topological stereoisomer have different three-dimension structures which result in its different functions in molecular recognition, assembly and aggregation. In this paper we reported four synthesized topological isomers whose chemical configurations were characterized by means of 1H NMR, 13C NMR, IR, UV and SEM. It is found that the topological configuration of C-shaped and S-shaped molecules can be identified by 1H NMR, and the topological isomers of S-shaped cis(SC)and trans(ST); C\|shaped cis(CC)and trans(CT)can be identified by 13C NMR. There is little difference in IR, UV and SEM of the four isomers.
