中文摘要：

在非协调的溶剂基于 α-aryl/alkoxy-substituted 锌酞毒(Pcs ) 的 J 聚集机制，二新奇偶氮苯酞毒二(3-azo-ZnPc 和 4-azo-ZnPc ) 与开发其形成 J 聚集的能力能调制相片的 Pc 混合物的目的被综合。在氯仿的 3-azo-ZnPc 能在一个宽范围是有效地控制相片的，这被发现。这现象能被变化在相片异构化过程期间在几何学和偶氮苯的偶极子时刻解释。4-azo-ZnPc 根本没有这个能力，与或没有紫外轻照明。aryl/alkoxy 替换相对被纳入的氧原子的位置在决定聚集能力被发现重要。

英文摘要：

Based on the J-aggregation mechanism of oParyl/alkoxy-substituted zinc phthalocyanines（Pcs） in non-coordinating solvents, two novel azobenzene-phthalocyanine dyads （3-azo-ZnPc and 4-azo-ZnPc） were synthesized with the aim of developing Pc compounds whose ability to form J-aggregation could be photo-modulated. It was found that 3-azo-ZnPc in chloroform could be effectively photo-controlled in a wide range. This phenomenon could be explained by the changes in the geometry and dipole moment of azobenzene during the photo-isomerization process. 4-azo-ZnPc did not have this ability at all, with or without UV light illumination. The positions of the oxygen atoms to which the aryl/alkoxy substitution was attached relatively were found important in determining the aggregation ability.
