新型酚氧基酞菁的合成及其光谱性质

采用醇锂法和插入法合成了三种α-（4-羟基苯氧基）₄酞菁(中心元素为2H,Zn或Mg)，产物经IR,UV-vis，¹H-NMR和MS表征。重点考察了三种化合物的两亲性，聚集性和光物理性质。结果表明，此类酞菁具有良好的两亲性，α位引入的对羟基苯氧基降低了在溶剂中的聚集程度，分子内光致电子转移使得荧光量子产率降低，有可能成为一种优良的Ⅰ型光敏剂。

Synthesis and spectral study of novel para-hydroxyphenoxy phthalocyanines

The synthesis of phthalocyanines(M=2H,Zn,Mg) substituted with para-hydroxy phenoxy groups was achieved by using n-pentanol,Li and 3-(4-hydroxyphenoxy)phthalonitrile both with and without the corresponding metal acetates.The structures were confirmed by IR,UV-visible,and 1H-NMR spectroscopy and MS.All the complexes were found to be very soluble in both high polarity solvents and low polarity solvents.The presence of the para-hydroxyphenoxy moieties in the compounds decreased their aggregation,and the quantum yields of fluorescence were reduced as a result of both the intramolecular photoinduced electron transfer and the internal conversion process.
