摘要
用一维１ Ｈ ＮＭＲ、１３Ｃ ＮＭＲ 方法研究了对甲氧基偶氮苯衍生物的结构， 并通过二维１ Ｈ－ １ Ｈ 同核相关谱（ＣＯＳＹ） 、１３ Ｃ－ １ Ｈ 异核相关谱（ ＨＥＴＣＯＲ） 及１３Ｃ－ １ Ｈ 异核远程相关谱进一步地确定了该类衍生物的１ Ｈ 谱和１３ Ｃ 谱中各谱峰的归属， 为研究侧链液晶聚合物结构提供了有价值的数据。
Structures of p _ methoxy _ azobenzene derivatives were studied by NMR. Their 1H and 13C spectra were assigned completely, which were further confirmed by 2D 1H _1H COSY, 13C _1H HETCOR and 13C _1H long _ range HETCOR methods. These results provide valuable data for NMR studies on the liquid crystal polymers containing such side _ chains.
