The synthesis of a new octa‐ tert ‐butylphthalocyanine is described. First, the 4,5‐di‐ tert ‐butylphthalonitrile building block was synthesized in a six‐step approach, in which the last step is a three reaction domino sequence. Then, this phthalonitrile was cyclotetramerized to furnish a new phthalocyanine dye, which presented no aggregation in solution and good photophysical properties.
