“…2 However, the efficiency of photo and electroluminescence of poly(thiophenes) themselves re mains low, if other fragments (most often based on phenyl ene) are not additionally included into their structure either as substituents at position 3 of the thiophene ring, or as com onomers during preparation of the polymers. At present, the best luminescent properties exhibit polymers based on 1,4 phenylenes themselves and their derivatives, in partic ular, poly(p phenylenevinylenes) 66 and poly(fluorenes).…”

General concepts of organic (polymeric) electronics are given, a relationship between chemical structure of semiconducting macromolecular systems and their electronic properties is considered, main approaches to the control of these properties are listed. A relationship between dimensionality of the systems considered (one , two , and three dimensional) and a possibility to control their molecular organization, as well as their practical use are illustrated. Typical representatives of both the linear and branched (two and three dimensional) macro molecules, approaches to the synthesis of such macromolecules, their optical and electrical properties, as well as prospective fields of application, are considered.

“…On the one hand, this can be explained by the necessity to develop fundamental knowledge about the mesomorphic state in general; on the other hand, by the unique physical and chemical properties of these compounds which are widely applied in different branches of science and technique, for example, as dyes, catalysts, sensors, matters for optical memory systems, solar cells and others. [1][2][3][4][5][6] One of the most important tasks while creating new molecular devices is to form a system of regulated structure [7,8] named 'molecular architecture'. Langmuir-Blodgett (LB) technology allows to solve this task.…”

In order to study the influence of molecular structure peculiarities on supramolecular organization and properties in the bulk and thin films of discotic mesogens six new mix-substituted phthalocyanine derivatives with 3,6-dioctyloxyphthalonitrile and 3,4,5,6-tetrachlorophthalonitrile fragments were synthesized. Temperatures of phase transitions, types of mesophase and their dependence on molecule structure, chemical nature, position and ratio of different substituents as well as presence of holmium in the metal complexes were analyzed. The behavior of the studied molecules on the boundary between water and air was investigated and the peculiarity of supramolecular organization in floating layers as well as in thin films was determined. Quenching of luminescence in solutions of the studied compounds in the presence of fullerene C 60 was determined, thus giving prospects for application of these compounds as sensors for fullerene microquantities.

“…At present these compounds are broadly used as dyes [1,2] in paint and varnish industry or color printing. The electrical and optical properties of metal phthalocyanines are actively used in photovoltaic solar cells [3], field-effect transistors and light-emitting diodes [4], liquid crystals [5], etc.…”
