Bisphthalonitriles linked by 2,2-disubstitutedpropan-1,3-diol precursors gave pure 1,11,15,25-substituted isomers of mononuclear phthalocyanine derivatives upon homocyclization. Reasonable yields of these phthalocyanines could be obtained with limited polymeric side-products utilizing modified cyclization methods. The 1H NMR spectrum of these phthalocyanines exhibited the discrete doublet-triplet-doublet proton signals expected of a pure isomer.
