Autor: Gen-ichi Konishi, Yuki Sawatari, Riki Iwai, Takuya Tanaka, Yoshimichi Shimomura, Masatoshi Tokita
Publikováno v: Molecules, Vol 29, Iss 21, p 5220 (2024)
In recent years, π-conjugated liquid crystalline molecules with optoelectronic functionalities have garnered considerable attention, and integrating these molecules into side-chain liquid crystalline polymers (SCLCPs) holds potential for developing

Publikováno v: Aggregate, Vol 5, Iss 3, Pp n/a-n/a (2024)
Abstract Supramolecular liquid crystals (SLCs) are attractive materials for fabricating devices with new optoelectronic functions. Conventional SLCs are made from hydrogen‐bonded mesogens. However, these mesogens suffer from high melting points, an

Publikováno v: Membranes, Vol 11, Iss 7, p 466 (2021)
Perfluorosulfonated ionomers are the most successful ion-exchange membranes at an industrial scale. One recent, cutting-edge application of perfluorosulfonated ionomers is in polymer electrolyte fuel cells (PEFCs). In PEFCs, the ionomers are used as

Alkylthio-based asymmetric liquid crystals: unravelling the substituent effects and intercalated cybotactic nematic and smectic phases
Autor: Yuki Arakawa, Yuko Ishida, Yukito Sasaki, Shunsuke Sasaki, Masatoshi Tokita, Hideto Tsuji
Publikováno v: Materials Advances. 3(No. 7):3218-3228
A homologous series of alkylthio- and alkoxy-based asymmetric calamitic liquid crystal (LC) molecules was developed. The effects of alkylthio groups on the phase transition properties and unexpected intercalated LC phase structures were studied.

Changing the structural and physical properties of 3-arm star poly(δ-valerolactone)s by a branch-point design
Autor: Hibiki Ogiwara, Takashi Kajitani, Takanori Fukushima, Fumitaka Ishiwari, Yukihiro Yamashita, Masaki Takata, Masatoshi Tokita, Tadahiro Kimura, Atsuki Sugimoto
Publikováno v: Chemical Communications. 57:3901-3904
The chemical structure of a branch point of star-shaped polymers has been considered to have a small influence on the physical properties of the entire polymer. Contrary to this general notion, here we show that a 3-arm star polymer, composed of thre
