Abstract
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.
