甲氧基苯氧基取代1：3和3：1不对称酞菁锌的合成及光谱性质

Synthesis of 1∶3 and 3∶1 methoxyphenoxy substiduted asymmetrical phthalocyanine zinc(Ⅱ) and spectrum characteristics

以4-硝基邻苯二腈和对甲氧基苯酚为原料合成了4-甲氧基苯氧基邻苯二腈,在醋酸锌存在条件下,再将4-甲氧基苯氧基邻苯二腈和邻苯二腈按1∶9和9∶1比例混合,反应后分别得到了β-一(4-甲氧基苯氧基)酞菁锌和β-三(4-甲氧基苯氧基)酞菁锌,通过IR光谱,紫外-可见光谱和质谱表征了其结构,并讨论了取代基数目对酞菁Q带最大吸收波长的影响,结果表明,取代基数目增多,其Q带最大吸收波长红移。

The 4-methoxyphenoxy-1,2-dicarbonitrile was synthesized employing 4-nitrobenzene-1,2-dicarbonitrile and p-methoxyphenol as major precursors. Under existence of the zinc acetate, the 4-methoxyphenoxy-1,2-dicarbonitrile and 1,2-dicarbonitrile were mixed by the ration of 1：9 and 9：1, respectively. The reaction major products were β-mono （4-methoxyphenoxy） phthalocyanine zinc and β-triple（4-methoxyphenoxy） phthalocyanine zinc, respectively. The structures of the products are characterized by IR, UV-vis and Mass spectrum. We discussed the influence of the substitute number on the maximum absorption wavelength of Q band. With the increasing of substitute number the Q band shifted to long wavelength.
