Visible absorption spectra have been recorded for azo compounds derived from 2,5-dichlorosulphanilic acid azo-coupled with ,-diethyl-m-phenylenediamine, and with azine analogues. The effects of the ring-aza substituents as well as cyano on the spectra indicate a surprising difference in sensitivity of the two ring positions meta to the azo group. M.O. calculations show chat the amino group ortho to
可见吸收光谱已被记录为从2,5- dichlorosulphanilic酸偶氮加上衍生的偶氮化合物,二乙基-间-苯二胺,并用吖嗪类似物。环氮杂取代基以及氰基对光谱的影响表明,两个环位置对偶氮基的敏感性都出乎意料的差异。MO的计算表明,偶氮键邻位的氨基将不对称性引入HOMO,这是造成取代作用不同的原因。
