摘要: 酞菁化合物的结构与卟啉类似,对光和热稳定性好,在可见光区有强的吸收,而且它还具有半导体性能和光生伏打效应。因此作为光导材料,信息记录和储存材料,以及在模拟光合作用研究光敏电子转移反应中作为光敏剂。引起人们广泛的兴趣。一般水溶性酞菁在水溶液中容易形成聚集体。

Abstract: The synthesis and aggregation of copper phthalocyanine having different alkoxy substi-tutents are described.In toluene-acetone solution, the existence of aggrgation are demonstrated in 1×10-5mol/L to 1×10-6mol/L concentration range.The result show that aggregation of CuPc depends on the nature of substitutent group, solvent polarity and central metal.The apparent aggregation constant and apparent aggregation number are determined.

Key words: phthalocyanine, apparent aggregation constant, apparent aggregation number
