Abstract
The influence of molecular structure of three unsymmetrically substituted phthalocyanine derivatives with 3,6-dioctyloxyphthalonitrile and 3,4,5,6-tetrachlorphthalonitrile fragments as well as their metal complexes with holmium, on luminescent properties in solutions and Langmuir — Blodgett (PLB) films was investigated. Comparison of absorption spectra of these compounds in thin films and chloroform solutions suggests that the compounds exhibit a greater tendency to association in films than in solutions. The study of luminescence spectra of phthalocyanine derivatives showed that the intensity of luminescence of the studied compounds in toluene solutions higher than in chloroform. Addition into solution of C₆₀ fullerene reduces intensity of luminescence.

Keywords: Langmuir — Blodgett films, asymmetrical phthalocyanine derivatives, molecular dynamics
