Производство этих устройств является перспективной и развивающейся отраслью промышленности. Анализ рынка жидкокристаллических устройств позволяет утверждать, что спрос на пленочные поляризаторы пропускающего, отражающего и пропускающе-отражающего типов будет возрастать в связи с постоянным ростом выпуска жидкокристаллических индикаторов и расширением сфер их применения. Исследования, направленные на создание пленочных поляризаторов различного функционального назначения и на разработку технологий их изготовления, актуальны. Нафталин-1,5-диамин широко применяется в производстве сложных промежуточных полупродуктов, красителей, химических добавок к полимерам, фармацевтических препаратов, пестицидов и др. Нафталин-1,5-диамин является доступным исходным соединением для получения на его основе перспективных соединений при создании оптических материалов и биологически активных соединений. Взаимодействием нафталин-1,5-диамина с замещенными альдегидами или бензальдегидами ванилинового ряда в среде кипящего абсолютного метанола в присутствии каталитических количеств ледяной уксусной кислоты были синтезированы (E,E)-азометины с выходами 75–87 %.</p></abstract><trans-abstract xml:lang="en"><p>Liquid crystal devices are widely used in measuring instrumentation, consumer and industrial electronics, medical, scientific and military equipment. The production of these devices is a promising and developing industry. Analysis of the market of liquid crystal devices suggests that the demand for film polarizers of transmission, reflection and transmission reflection types will increase due to the constant growth of production of liquid crystal indicators and the expansion of their applications. Studies aimed at the creation of film polarizers for various functional purposes and the development of technologies for their manufacture are relevant. Naphthalene-1,5-diamine widely used in the production of complex intermediate intermediates, dyes, chemical additives to polymers, pharmaceuticals, pesticides, etc. Naphthalene-1,5-diamine is an available starting compound for obtaining on its base promising substances for the development of optical materials and biologically active compounds. By interaction of naphthalene-1,5-diamine with substituted aldehydes or benzaldehydes of vanillin series in the medium of boiling absolute methanol in the presence of catalytic amounts of glacial acetic acid, (E,E)-diazomethines with yields of 75–87 % were synthesized.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>нафталин-1</kwd><kwd>5-диамин</kwd><kwd>альдегиды</kwd><kwd>(E</kwd><kwd>E)-диазометины</kwd><kwd>красители</kwd><kwd>квантово-химические расчеты</kwd><kwd>моделирование</kwd><kwd>жидкокристаллические индикаторы</kwd><kwd>поляризационные свойства</kwd></kwd-group><kwd-group xml:lang="en"><kwd>naphthalene-1</kwd><kwd>5-diamine</kwd><kwd>aldehydes</kwd><kwd>(E</kwd><kwd>E)-diazomethines</kwd><kwd>dyes</kwd><kwd>quantum-chemical calculations</kwd><kwd>simulation</kwd><kwd>liquid crystal displays</kwd><kwd>polarization properties</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Белорусского республиканского фонда фундаментальных исследований (грант Х16-021).</funding-statement><funding-statement xml:lang="en">This work has been performed with a financial support of Belarusian Republican Foundation for Fundamental Research (Grant № Х16-021).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Филиппович, Л.
