    Liquid crystalline triphenylene derivatives, TPC1p-n (n = 6, 12, 14, 16) were prepared using p-alkoxycinnamate as the [2+2] photo-cyclization site. TPC1p-n (n = 12, 14, 16) showed Colr phase and gave crescent-shaped or helical fibers after UV-irradiated in liquid paraffin solutions at 90 and 110 °C in the Colr temperature range. The apparent photoreaction products were shown to be thermally reversible, i.e. they dissolved in liquid paraffin at high temperatures and reappeared on cooling, indicating that they were aggregates of oligomerized TPC1p-n. The reaction mechanism was discussed in terms of the structure of the liquid crystalline phase.

    In this study, we have disclosed intriguing electrochromic properties of 6-aryl-1,3-bissilylfulvenes. The electrolyte solutions (0.1 M n-Bu4NClO4 in acetonitrile or dichloromethane) of some 6-aryl-1,3-bissilylfulvenes showed notable color changes when superimposed negative voltages were applied to the solutions. Investigation of the substituents at position 6 revealed that the solution of 1,3-bissilyl-6-anthracenylfulvene exhibited chromic changes under both applied superimposed negative and positive voltages and exhibited a three-color electrochromism. Electrochromic properties of 1,6-diarylfulvenes derived from 6-aryl-1,3-bissilylfulvenes were also investigated. The aryl group at position 1 also contributed to the electrochromism of fulvenes.

  • PB18 Synthesis and Characterization of Discotic Liquid-Crystalline Compounds Having Trialkylsilyl Groups               
    Miyazaki Yutaro; Yasutake Mikio; Hirose Takuji
    Number:2012, First page:"PB18, Last page:1"-"PB18-2", 20 Aug. 2012
    Novel discotic liquid-crystalline materials were synthesized from triphenylene and hexabenzocoronene by attaching trialkylsilyl groups in the side chains. These compounds dissolved well in hexane, toluene, chloroform, diethyl ether and THF. DSC, POM and XRD measurements proved that triphenylene and hexabenzocoronene derivatives exhibit Col r and Col ho masophases respectively, over wide temperature ranges. Trialkylsilyl group was shown to be an effective flexible moiety of liquid-crystalline materials to improve solubility in organic solvents.

    In order to develop columnar discotic liquid-crystalline compounds with high charge transport ability, a pyrene derivative having a thiophene moiety in the side chains was synthesized and the physical and thermal properties were studied by POM, DSC, and XRD measurements. It was shown that an ordered hexagonal columnar (Col_) phase appears in the temperature range of more than 130 degrees showing the liquid crystalline phase is stable. The hole mobility determined by the time-of-flight (TOF) method was 4.8×10^<-3>cm^2V^<-1>s^<-1> in the Col_ phase at 140℃.

    We were designed four kinds of liquid crystal materials having pyrendithione and bithiophene moieties and synthesized. And their liquid crystalline properties were also investigated. Furthermore, we investigated the electrochromic properties of PQBTs in the solutions. After, the electrochromic devices using PQBTs were formed, and this was also examined. In particular, the electrochemical properties of PQBTs in solution were better than those previously reported and showed electrochromic properties over a wide range of potentials. In addition, the PQBTs devices showed electrochromic characteristics of three colors. In addition, we also investigated the switching speeds of these and examined their repeatability.

    Two kinds of liquid crystal compound having an anthraquinone and bithiophene moieties were synthesized. The mesophases exhibited, have been characterized by means of polarized optical microscopy observation (POM), differential scanning calorimetry (DSC), X-ray diffraction (XRD) studies. The observation results, those phase was lamellar phase. Furthermore, those electrochemic properties were examined by cyclic voltammetry (CV). And the electrochromism of the liquid crystal compounds was also examined by UV-vis spectra.Moreover, the electrochromic devices were made and the color property in the electrochemistry was observed.
    Finally mixture of an ionic liquid crystal and an electrochromics material was prepared, and it was examined. However, they caused phase separation.
