Synthesis and Some Properties of Aryl- and Aryloxy-Substituted Phthalocyanines and Their Metal Complexes: A Comparison with Porphyrazine and Naphthalocyanine Analogues

On the basis of new results from a study with more phthalocyanines, the assignments of some 13C NMR signals of the two phthalocyanines, given in Figure 5 of the original article,[1] must be changed. Thus, signals assigned as 3, 7 and 6 for compound 7b should be assigned as 7, 6 and 3, respectively. Similarly, for compound 7a the assignment of 3 and 7 should be inverted.
