可溶性杂化结构金属酞菁衍生物的合成及其吸收光谱

Synthesis and Absorption Spectra of Soluble Hybrid Metal Phthalocyanine Derivatives

3-叔丁基苯氧基邻苯二腈或4-叔丁基笨氧基邻苯二腈分别与6-叔丁基萘-2,3-二腈以不同物质的量之比混合后在正戊醇(含DBU)中与无水氣化亚铜或无水氯化锌反应,生成可溶性铜酞菁或辞酞菁的衍生物,产物是一个混合物,其中既有非杂化构造的AAAA型和BBBB型结构的产物,又有杂化构造的ABBB型、AABB型和ABBB型结构的产物。它们在DMF、二氣甲烷、乙二醇单乙醚和乙二醇单丁醚中的溶解性很好,吸收Q带的峰形相对于结构单一的金属酞菁衍生物明显宽化,其中,强吸收峰由单一的尖峰变为双尖峰或三尖峰,取决于两种二腈化合物间的混合比,强吸收波段几乎覆盖650~780 nm。

The soluble copper phthalocyanine or zinc phthalocyanine derivatives were obtained through the mixtures of 3-tert-butylphenoxyphthalonitrile or 4-tert-butylphenoxyphthalonitrile with 6-tertbutylnaphthalene-2,3-dinitrile,reacted with the anhydrous cuprous chloride or anhydrous zinc chloride in n-pentanol(containing DBU)at different molar ratios.The product was a mixture that contained both non-hybrid AAAA and BBBB molecules and hybrid ABBB,AABB and ABBB molecules which were soluble in DMF,dichloromethane,ethylene glycol monoethyl ether and ethylene glycol monobutyl ether.The shape of light absorption curve in the visible light region(Q band)was wider than that of nonhybrid metal phthalocyanine derivatives.The strong absorption peak changed from single peak to double peaks or triple peaks,depending on the mixing ratio of the two dinitrile compounds,while the strong absorption band almost covered the range of 650-780 nm.
