摘要：

The first example of an antiaromatic expanded phthalocyanine, classified as a norcorrole of a superphthalocyanine has been prepared and fully characterized. The newly developed phthalonitrile dimerization reaction was a crucial step, which allowed for the bottomup synthesis of expanded phthalocyanines. Their structure was confirmed by single crystal X-ray diffraction analysis. The 20 pi antiaromaticity of the macro cycles was suggested by optical and theoretical calculations.
