It was shown that the presence of a metal in a macromolecule affects the electric conductivity of oligo-and polyphthalocyanines. A change in the electric conductivity related to introduction of the metal does not exceed two orders of magnitude and depends on the nature, concentration, and location of the metal in the macromolecule (in the window of the azaporphine ring or in the outer sphere). This change does not mask the dependence of electric conductivity on the length of conjugation regions in macromolecules that was established for metal-free products. It was demonstrated that the electric conductivity drops upon incorporation of urea fragments into the molecular structure of polyazaporphine owing to violation of the continuous conjugation chain. The role of end groups of macromolecules in the appearance of barriers to intermolecular electronic transport in the electrical conduction process was revealed.

Formylation of photochromic 9′-hydroxy-1,3,3-trimethyl-1,3-dihydrospiro[2H-indole-2,3′-3′H-naphtho[2,1-b][1,4]oxazine] with the paraformaldehyde-MgCl2-Et3N system or by the Reimer-Tiemann reaction proceeds at the ortho-position to the hydroxy group to form 10′-formyl derivative.
