Naphthalocyanines (Nc’s) are in focus of interest as - extended phthalocyanine derivatives with absorbance in NIR range, that affords their application as materials for optoelectronics, nonlinear optics, etc. One of the main problems of naphthalocyanines is their high tendency to aggregation leading to low solubility, fast deactivation of the excited states and ability of singlet oxygen generation. In this work the novel tetra(15-crown-5)substituted Ncs bearing heptyl and heptynyl groups were synthesized. Copper(II) was chosen as a central cation because of the photostability of Cu(II) phthalocyanines. The complexes were obtained from corresponding naphthalonitriles by template reactions. It was shown that application of Cu(I) salts in this reaction is more effective than Cu(II) probably because of the high tendency to oxidation of naphthalocyanines.
