The commercial application of polymer blend technology has grown significantly such that, today, compositions are available with properties that once were substantially unattainable with homopolymers. To date, polymer blends have been applied in optical fibers [13,14], microlenses [15], liquid crystal display components [16,17], solar cells [18-20], nonionizing radiation detection [21] and polymer light-emitting diodes [22-24]. In particular, the use of developed polymer blends in optoelectronics applications appears unlimited. Polymer blends may also provide model systems in statistical physics when studying the fundamental aspects of equilibrium and nonequilibrium properties [3], optical properties [25], and mechanical and electrical properties [26].

As in the case of [3]radialenes, the individual redox stages of [4]radialenes may have different colors. Based on these electrochromic properties, the application of 77 as a component in liquid crystal display devices was patented85. 

Thermotropic cholesterics have several practical applications, some of which are very widespread. Most of the liquid crystal displays produced use either the twisted nematic (see Figure 7.3) or the supertwisted nematic electrooptical effects.6 The liquid crystal materials used in these cells contain a chiral component (effectively a cholesteric phase) which determines the twisting direction. Cholesteric LCs can also be used for storage displays utilizing the dynamic scattering mode.7 Short-pitch cholesterics with temperature-dependent selective reflection in the visible region show different colors at different temperatures and are used for popular digital thermometers.8...

Perfluoropropenylcyclohexane-containing liquid crystals, (IV), prepared by Kato [4] were used as components in liquid crystal display elements. 

NQC A chemical used as the raw material of a photosensitive substance, which is one of several components of a photoresist used in the manufacturing process of semiconductors or liquid crystal displays. 

Stretch-oriented poly(vinyl alcohol) films which contain iodine are essential light polarizing components in today s liquid crystal displays (LCDs). They do, however, suffer from the inherent diffusion and sublimation problems of iodine and its chemical aggressiveness. The latter also prevents realization of new LCD... 

Many portable instruments have been made possible by the use of clever designs incorporating smaller components, for example optical fibres, light emitting diodes (LEDs), liquid crystal displays (LCDs) and miniature gratings for use in spectrometers, each of which are discussed below. These developments, amongst others, have contributed immensely to the development of the whole area of portable analytical instruments. They have seen particular use in portable electrochemical and spectrometric instruments. 

Liquid Crystals. Ferroelectric Hquid crystals have been appHed to LCD (liquid crystal display) because of their quick response (239). Ferroelectric Hquid crystals have chiral components in their molecules, some of which are derived from amino acids (240). Concentrated solutions (10—30%) of a-helix poly(amino acid)s show a lyotropic cholesteric Hquid crystalline phase, and poly(glutamic acid ester) films display a thermotropic phase (241). Their practical appHcations have not been determined.
