    Thermally-Induced Phase Transition of Pseudorotaxane Crystals: Changes in Conformation and Interaction of the Molecules and Optical Properties of the Crystals

    No full text
    This paper presents a pseudorotaxane that acts as a thermally driven molecular switch in the single-crystal state. Crystals of the cationic pseudorotaxane consisting of dibenzo[24]­crown-8 (DB24C8) and <i>N</i>-(xylylammonium)-methylferrocene as the cyclic and axle component molecules, respectively, undergo crystalline-phase transition at 128 °C with heating and 116 °C with cooling, according to differential-scanning-calorimetry measurements. X-ray crystallographic analyses revealed that the phase transition was accompanied by rotation of the 4-methylphenyl group of the axle component molecule and a simultaneous shift in the position of the PF<sub>6</sub><sup>–</sup> counteranion. Crystalline phase transition changes the conformation and position of the DB24C8 molecule relative to the ammonium cation partially; the interaction between the cyclic component and the PF<sub>6</sub><sup>–</sup> anion in the crystal changes to a greater extent. Moreover, there are changes in the vibration angle (θ) and birefringence (Δ<i>n</i>) on the (001) face of the crystal transitionally; θ is rotated by +12°, and Δ<i>n</i> is decreased from 0.070 to 0.059 upon heating across the phase transition temperature. The phase transition and accompanying change in the optical properties of the crystal occur reversibly and repeatedly upon heating and cooling processes. The switching rotation of the aromatic plane of the molecule induces a change in the optical anisotropy of the crystal, which is regarded as a demonstration of a new type of optical crystal. Partial replacement of the PF<sub>6</sub><sup>–</sup> anion with the bulkier AsF<sub>6</sub><sup>–</sup> anion forms crystals with similar crystallographic parameters. An increase in the AsF<sub>6</sub><sup>–</sup> content decreases the reversible-phase-transition temperature gradually down to 99 °C (<i>T</i><sub>end</sub>) and 68 °C (<i>T</i><sub>exo</sub>) ([AsF<sub>6</sub><sup>–</sup>]:[PF<sub>6</sub><sup>–</sup>] = 0.4:0.6)

    Production of a thermal stress resistant mutant <i>Euglena gracilis</i> strain using Fe-ion beam irradiation

    <p><i>Euglena gracilis</i> is a common phytoplankton species, which also has motile flagellate characteristics. Recent research and development has enabled the industrial use of <i>E. gracilis</i> and selective breeding of this species is expected to further expand its application. However, the production of <i>E. gracilis</i> nuclear mutants is difficult because of the robustness of its genome. To establish an efficient mutation induction procedure for <i>E. gracilis</i>, we employed Fe-ion beam irradiation in the RIKEN RI beam factory. A decrease in the survival rate was observed with the increase in irradiation dose, and the upper limit used for <i>E. gracilis</i> selective breeding was around 50 Gy. For a practical trial of Fe-ion irradiation, we conducted a screening to isolate high-temperature-tolerant mutants. The screening yielded mutants that proliferated faster than the wild-type strain at 32 °C. Our results demonstrate the effectiveness of heavy-ion irradiation on <i>E. gracilis</i> selective breeding.</p> <p>The procedure of screening of mutant <i>Euglena gracilis</i> strain. With this procedure thermal stress resistant strains were segregated.</p
