The functional materials – polyvinyl chlorides (PVC)-films and sorbent for gas chromatography – on the base of complexes of substituted phthalocyanines copper and nickel was studied. On the basis of PVC many products are manufactured. As results of photodegradation under the influence of UV radiation, the material’s physico-mechanical properties are worsened, transparency is reduced, and color changes occur. To ensure a high level of fade resistant products of PVC three compounds CuPc(4-t-Bu)₄ , CuPc(3-NO₂)₄(5-t-Bu)₄ , CuPc(4-t-Bu)₄(5-NO₂)₄ were synthesized. Film samples used for this study were obtained from a 12 % solution in cyclohexane dried formation. The composition of substituted copper phthalocyanines were 0.5 mass content in 100 mass content of PVC each. The obtained samples were subjected to photo treatment under CES-375 lamp, at 375 Watts power, at a distance of 20 cm at 25 °С for 24, 48 and 72 hours. The electron absorption spectral prior and after the photo treatments of CuPc(4-t-Bu)₄, CuPc(3-NO₂)₄(5-t-Bu)₄, CuPc(4-t-Bu)₄(5-NO₂)₄ pigmented film samples were registered by Shimadzu UV-2550 (Japan). Experimental data obtained demonstrated the immutabilities of the maxima even after 72 hours exposure under powerful UV radiation. Due to these high photostabilities and good compatibility with PVC, CuPc(4-t-Bu)₄ and CuPc(3-NO₂)₄(5-t-Bu)₄ can be used as pigmenting substances in the production of PVC-materials. The stationary phase for gas chromatography on the basis of NiPc(4-t-Bu)₄(5-NO₂)₄ was studied. Chromatographic tests were carried out using “Shimadzu” GH-2014. Stationary phase was placed on the solid sorbent Chromaton N-AW (0.40-0.63). Degree of impregnation was 7.8 %. Metal column with length 1 m was used. Xylene, lutidin and picolin isomers were used as nonmesomorphic sorbates. The retention times for these sorbates were measured. The values of retention volumes were calculated. The decrease of retention volumes at increasing temperature was shown. The structural selectivity of the stationary phase on the basis of NiPc(4-t-Bu)₄(5-NO₂)₄ was determined.
