Abstract
Statistical condensation of 4’,5’-dicyanobenzo-15-crown-5 and 4,5-dibutoxyphthalonitrile in the presence of Mg2+ as a template led to a mixture of complexes, which was separated to isolate mono-crown-substituted magnesium phthalocyaninate Mg[(15C5)(BuO)6Pc]. Its demetallation afforded corresponding metal-free ligand, H2[(15C5)(BuO)6Pc]. Aggregation of this phthalocyanine was studied both in concentrated solutions (up to 1.32·10-3 M in chloroform), or in the presence of potassium acetate. Application of nonlinear regression for analysis of spectrophotometric data provided evidences of dimerization of phthalocyanine molecules under these conditions. Architecture of dimers is discussed.
