Structural peculiarities of mesogenic phthalocyanines and their derivatives are considered. Liq uid crystalline materials based on self assembled phthalocyanine molecules are promising novel functional materials for sensors, as catalysts, optically and bioactive matrices, and semiconductor cells. Mesomorphic and electrophysical characteristics of liquid crystalline phthalocyanine based materials are considered, pos sibilities of their use are discussed, and the structure-property relations are analyzed.

Тонкие химические технологии / Fine Chemical Technologies 2017 том 12 № 3 Определениe фенольных соединений в дезинфекционных средствах components. The literature data and experimental results suggest that it is more efficient to analyze the whole series of disinfectants in isopropanol (sometimes in water) by chromatographic methods, preferably by HPLC. Sample preparation reduces to the solubilization of batches of ready-made disinfectants in isopropanol/water. It is optimal to carry out the chromatographic study using elution with acetonitrile-based systems (for example, СН 3 СN:Н 2 O, 60:40) providing the correct determination (λ = 280 nт) of phenol derivatives. The completeness of extraction (if the extraction method is used), as well as the metrology aspects of all the analytical determination is set directly in а laboratory during the realization of procedures of introduction/validation according to the internal documents of the system quality management for the relevant structural unit.
