采用分光光度法研究了磺化酞菁在不同醇、水混合溶液中的二聚现象.结果表明:三磺化酞菁、四磺化酞菁钴的二聚常数 K_D 与溶液中 O—H浓度 M_(O—H)之间满足关系 lgK_D=a·M_(O—H)~(+b),式中 a,b是与磺化酞菁配合物有关的参数。
The dimerization of sulfonated phthalocyanine in different alcohol and water mixed solutions was studied by spectrophotometry.The results showed that the dimerization constant K_D of trisulfonated phthalocyanine and tetrasulfonated phthalocyanine cobalt and the O-H concentration in solution M_ (O-H) satisfy the relationship lgK_D = a · M_ (O-H) ~ (+ b), where a and b are parameters related to the sulfonated phthalocyanine complex.
