一种两亲性酞菁的合成及其光谱研究

Synthesis of an amphiphilic substituted phthalocyanine and study on its spectra

用硅胶负载法合成了一种两亲性不对称取代酞菁三-α-(2,2,4-三甲基-3-戊氧基)-β-(4'-羧基苯氧基)酞菁铜.紫外可见吸收光谱的研究表明,与脂溶性的四-α-(2,2,4-三甲基-3-戊氧基)酞菁铜相比,该两亲性酞菁的最大吸收波长和吸收带的形状受溶剂的影响更大,在水中其聚集态可以被阳离子表面活性剂解聚,而受阴离子表面活性剂的影响不大.

A amphiphilic substituted phthalocyanine, tri-α-(2, 2, 4-trimethyl-3-pentoxy)-β-(4'- carboxyphenoxy)phthalocyaninatocopper was synthesized by the polymeric support method on silica gel. Compared with the lipophilic tetra-α-(2, 2, 4-trimethyl-3-pentoxy)phthalocyaninatocopper, the shape and λ_(max) of Q band of the amphiphilic phthalocyanine are more sensitive to solvents and the agg\|regation can be released by a cationic surface-active agent (CTAB) but not by an anionic surfactant.
