The use of asymmetricphthalocyanines (Pcs) as platforms for the preparation of several asymmetric hexatriazolyl-monohydroxyphthalocyanines via copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) reaction was investigated. Asymmetric Pcs 5a and 5b were prepared through statistical macrocyclization of phthalonitriles (Pns) 1a and 2 to give PMB-protected 4a and 4b, which afforded asymmetric Pcs 5a and
