1. Yimin Liang, Teppei Yamada, Hongyao Zhou, Nobuo Kimizuka, Hexakis(2,3,6-tri-
O -methyl)-α-cyclodextrin-I

complex in aqueous I

thermocells and enhancement in the Seebeck coefficient, Chemical Science, 10.1039/c8sc03821j, 10, 3, 773-780, 2019.01, A large Seebeck coefficient (S
) of 1.9 mV K
was recorded for the I

thermocell by utilizing the host-guest complexation of hexakis(2,3,6-tri-O-methyl)-α-cyclodextrin (Me
-α-CD) with the oxidized iodide species. The thermocell measurement and UV-vis spectroscopy unveiled the formation of an Me
-α-CD-pentaiodide (I

) complex, which is in remarkable contrast to the triiodide complex α-CD-I

previously reported. Although the precipitation of the α-CD-I

complex in the presence of an electrolyte such as potassium chloride is a problem in thermocells, this issue was solved by using Me
-α-CD as a host compound. The absence of precipitation in the Me
-α-CD and I

system containing potassium chloride not only improved the S
of the I

thermocell, but also significantly enhanced the temporal stability of its power output. This is the first observation that I

species is formed in aqueous solution in a thermocell. Furthermore, the solution equilibrium of the redox couples was controlled by tuning the chemical structure of the host compounds. Thus, the integration of host-guest chemistry with redox couples extends the application of thermocells..

Masaya Matsuki, Teppei Yamada, Nobuhiro Yasuda, Shun Dekura, Hiroshi Kitagawa, Nobuo Kimizuka, Nonpolar-to-Polar Phase Transition of a Chiral Ionic Plastic Crystal and Switch of the Rotation Symmetry, Journal of the American Chemical Society, 10.1021/jacs.7b10249, 140, 1, 291-297, 2018.01, The synthesis of a new ionic plastic crystal, tetraethylammonium-d20 d-10-camphorsulfonate, is reported. The crystal has three solid phases, the structures of which were determined by single-crystal X-ray diffraction (XRD). XRD analysis revealed a phase transition from nonpolar space group P21212 to polar space group P21 with increasing temperature. The dynamics of the d-10-camphorsulfonate anion and the tetraethylammonium-d20 cation was investigated by variable-temperature 1H and 2H solid-state NMR spectroscopy. The anion showed swing motion in high-temperature phases, which is in good agreement with the disorder observed in XRD analysis. The cation showed uniaxial rotation even in the low-temperature phase. The rotation axis of the tetrahedral structure showed a transition from the two-fold axis to the three-fold axis with the phase transition..
3. H. Zhou, Teppei Yamada, Nobuo Kimizuka, Thermo-electrochemical cells empowered by selective inclusion of redox-active ions by polysaccharides, Sustainable Energy and Fuels, 10.1039/c7se00470b, 2, 2, 472-478, 2018.01, Thermo-electrochemical cells (TECs) are a class of thermoelectric materials that offer high thermoelectric voltage (Seebeck coefficient) with potentially lower costs compared to the conventional thermoelectric materials. To maximize the potential of TECs, we show that the Seebeck coefficient of TECs with a redox pair of I

is enhanced by introducing polymer-ion interactions. Starch and polyvinylpyrrolidone (PVP) are employed as polymeric hosts for I

ions. The effective concentration of free I

ions in the cold cell decreases due to their selective inclusion in host polymers, resulting in an increase of the [I

] ratio. Meanwhile in the higher temperature cell, the inclusion of I

ions by host polymers is less effective and the [I

] ratio is mostly determined by the intrinsic equilibrium without polymers. Consequently, the two electrode cells differing in temperature show a considerable difference in the concentration of I

ions, which causes a significant increase of the Seebeck coefficient up to 1.5 mV K
. The performance of polymer TECs can be tuned depending on the polymer-I

interactions, and starch showed notable performance as compared to PVP, with increased output power by a factor of two..
