| Summary: | 碩士 === 國立交通大學 === 材料科學與工程學系 === 98 === In this research, we successfully synthesized a series of banana-shaped hydrogen-bonded liquid crystalline molecules, containing either single or double-membered benzene rings, in order to obtain broader temperature ranges of SmCPF phase (SiA-PyBVF14). Furthermore, these banana-shaped hydrogen-bonded liquid crystalline molecules were doped with gold nanoparticles, which were surface-modified by banana-shaped liquid crystalline surfactant through thiol bonding. Correspondingly, we investigated the liquid crystalline behavior both before and after doping of nanoparticles by dint of a variety of instruments, such as POM, DSC, XRD and optical-electro measurement. More importantly, we acquired a well-structured liquid crystalline phase by an in-situ electric-field induction monitored through XRD.
