反式和顺式-1，2-二氰-（4-乙基苯）乙烯结构的谱学分析

合成了2种新型的可溶性四氮杂卟啉中间体：反式-1，2二氰-（4-乙基苯）乙烯和顺式-1，2-二氰（4-乙基苯）乙烯。通过UV-Vis，FFIR，GC／MS，^1H NMR等方法对这2种化合物的结构进行了表征，给出了它们完整的结构信息。分析比较了顺、反异构体结构上的差异，分析两者的紫外-可见光谱（UV-Vis）、红外光谱（FTIR）和核磁共振光谱（^1H NMR）谱图的差异及其产生原因。

Two precursors of soluble tetraazaporphrins, trans-1,2-dicyano-(p-ethylphenyl)alkene and cis-1,2-dicyano-(p-ethylphenyl)alkene, were synthesized. Their structures were confirmed by elemental analysis, FTIR, UV-Vis, GC/MS and H-1 NMR. The differences in isomer structures of the trans and cis-1,2-dicyano-(p-ethylphenyl)alkenes were represented by the obvious differences in the spectra of UV-Vis, FTIR and H-1 NMR In addition, the reasons for the differences were also analyzed.
