| Abstract: | The aggregation properties of zinc phthalocyanines substituted with alkoxy chain of various length were studied. It is believed that the driving force of aggregation is hydrophobic interaction. The critical solvent composition for aggregation cΦ and critical aggregate concentration CAC as well as average aggregate number (n) and aggregate constants (K) were determined. It was found that the phthalocyanine with straight long alkoxy chains prefer to form dimers in THF-H2O mixed solvent, the longer the alkoxy chain, the stronger the aggregation tendency with higher aggregation constant. |
