摘要: 采用分光光度法研究了磺化酞菁镓的二聚现象;测定了二聚常数kd,讨论了PH值、离子强度、水、温度等因素对kd的影响,研究结果表明:磺化酞菁镓的二聚反应可表示成:2SPcGaOH⇔(SPcGa)2O+H2O 且磺化酞菁镓的二聚常数随着离子强度、磺酸基数目、水的浓度的增加而增加。

Abstract: The aggregation of Ga-sulfopthlocyanine has been studied.Dimerization constantsare reported.The effects of pH, ionic strength,water,temperature, and sulfonation numberon the aggregation are also discussed.The experimental results show that Ga-sulfophth-alocyanine aggregative reaction can be expressed as follows: 2SPcGaOH⇔(SPcGa)2O+H2O It also shows that the greater the ionic strength,the sulfonation number,and the concentration of water the greater the dimerization constants of Ga-sulfophthalocyanine willbe.

Key words: gallium, phthalocyanine, aggregation, spectrophotometry
