Two benzothiadiazole-based liquid crystalline polyacrylates were synthesized. These polymers revealed a nematic liquid crystal phase and exhibited photoluminescence as well as polarized electroluminescence when incorporated into light-emitting diode applications. The polymers showed dichroic ratios of about 8.3–8.8 in UV-vis absorption and photoluminescence emission. The polymer with vinylene linkages (P2) showed better electroluminescence device performance than that with acetylene linkages (P1). The P2 device emitted red light at 604 nm with a turn-on voltage at 6 V, and a maximum polarized luminance of 235 cd/m2 at 12 V, with an efficiency of 0.09 cd/A and a polarization ratio of 6.5. 相似文献

Metal nanoparticles are now creating a new class of materials that are different from either conventional bulk materials or atoms, giving one of the smallest building blocks of matter. Metal nanoparticles have various properties based on high surface area and quantum size effects. Here we focus on the application of metal nanoparticles to liquid crystal displays, which is providing a new field in science and technology. The doping of nanoparticles into liquid crystal materials induces the modification of almost all of the physical properties of the liquid crystal, causing a reduction in the response time of liquid crystal displays. These techniques may be an alternative approach for improving the properties of liquid crystals other than chemical synthesis. 相似文献

Colloidal semiconductor nanocrystals (NCs), or quantum nanostructures with various dimensions and morphologies, are excellent emerging solution‐processable luminescent materials for display applications. The future of semiconductor NCs in the display market strongly relies on the development of low energy consuming devices. Replacing spherical NCs with multi‐dimensional nanostructures that emit linearly or circularly polarized light with high color purity and brightness, can significantly enhance the performance and efficiency of future display devices. In this review, we highlight some recent advances of colloidal syntheses of multi‐dimensional quantum nanostructures and their implementation as polarized light sources. The most representative examples are quasi‐one‐dimensional (q‐1D) CdSe/CdS dot‐in‐rods with strong linearly polarized emission for liquid crystal display technologies, and two‐dimensional (2D) nanoplatelets with enhanced circular dichroism signals as potential circularly polarized luminescence sources for electroluminescence applications. 相似文献
