用核磁共振表征对硝基偶氮苯衍生物

Nuclear Magnetic Resonance Characterization of p-Nitrophenyl Azobenzene Derivatives

用一维１Ｈ ＮＭＲ、１３Ｃ ＮＭＲ方法研究了对硝基偶氮苯衍生物的结构，并通过二维１Ｈ－１Ｈ同核相关（ＣＯＳＹ）、１３Ｃ－１Ｈ异核相关（ＨＥＴＣＯＲ）及１３Ｃ－１Ｈ异核远程相关谱进一步地确定了该衍生物的１Ｈ谱和１３Ｃ谱中各谱峰的归属．为研究侧链液晶聚合物结构提供了结构数据。

H and 13C NMR spectra of p-nitrophenyl azobenzene derivatives were completely assigned by using 1D 1H and 13C methods, which were further confirmed by 2D 1H -1H COSY, 13C-1H HETCOR and 13C-1H long-range HETCOR methods. These results would be a foundation for NMR studies of the liquid crystals containing such side-chains.
