The synthesis of a series of novel tetra-(benzo-24-crown-8)-phthalocyanines (Mg(II), Ni(II) and Co(II)) as well as a modified procedure for the free-base ligand and its Zn(II) and Cu(II) complexes are reported. The tendency of these phthalocyanines to undergo supramolecular cofacial dimerization induced by interaction with a viologen (N,N-di(but-3-ynyl)-4,4′-bipyridinium) was investigated by UV-vis absorption and EPR spectral studies in solution. The nature of the metal cation in phthalocyanine, the concentration, as well as the solvent all influenced the assembly processes.

Tetra-(benzo-24-crown-8)-phthalocyanines 作为超分子系综的平台：合成和与紫精的相互作用

一系列新型四-(benzo-24-crown-8)-酞菁（Mg(II)、Ni(II) 和 Co(II)）的合成以及游离碱配体的改进方法及其报道了 Zn(II) 和 Cu(II) 配合物。这些酞菁倾向于发生由与紫精相互作用引起的超分子共面二聚化（ñ,ñ-di(but-3-ynyl)-4,4'-联吡啶鎓)通过溶液中的紫外-可见吸收和EPR光谱研究进行研究。酞菁中金属阳离子的性质、浓度以及溶剂都会影响组装过程。
