WebAbstract A copper nanoparticle–sulfuric disazo dye (Cu–SD1) composite was synthesized using the sol–gel method. Cu–SD1 nanocomposite formation was monitored by ultraviolet-visible spectroscopy (UV-vis). The acquired experimental results suggested that 8 h of reaction is needed for the synthesis Cu 0 nanoparticles. WebAbstract. In this article, we disclose a method to achieve submicron-scale resolution for liquid crystals by photo-alignment of the sulfonic azo dye (SD1) layer. The interference pattern produced by Lloyd’s mirror has been used to produce two alignment domains. The easy axes in these alignment domains are mutually perpendicular to each other ...

Photo-induced molecular alignment of azo dye derivative

WebSep 4, 2024 · The application of SD-1 material provides an excellent alignment of LC molecules inside cylindrical structures and improves switching times in PCFs infiltrated with LCs [ 17 ]. In recent years, a significant amount of research reports has been devoted to another improvement of LC-based systems. Webconcentration of P.I., azo dye and LCP monomer in the solution preparation. The ideal case is the aligning speed of SD1 should be faster than the polymerization speed of LCP during the single-shot exposure. Otherwise, the film will poorly align due to the failure rotation of SD1 molecules after LCP is fully polymerized.
