Bent-Core Liquid Crystals: Their Mysterious and Attractive World
Hideo Takezoe,Yoichi Takanishi +1 more
TL;DR: In this article, structural and properties of liquid crystalline phases formed by bent-core molecules are reviewed and the most attractive properties of this new class of liquid crystals are in polarity and chirality, despite being formed from achiral molecules.
Journal ArticleDOI
Antiferroelectric chiral smectic liquid crystals
TL;DR: In this paper, the authors have suggested the pair formation of transverse dipole moments in adjacent smectic layers as the cause of antiferroelectricity in liquid crystals.
Journal ArticleDOI
Electro-tunable optical diode based on photonic bandgap liquid-crystal heterojunctions.
Jisoo Hwang,Myoung Hoon Song,Byoungchoo Park,Byoungchoo Park,Suzushi Nishimura,Takehiro Toyooka,Jeong Weon Wu,Yoichi Takanishi,Ken Ishikawa,Hideo Takezoe +9 more
TL;DR: A new hetero-PBG structure consisting of an anisotropic nematic layer sandwiched between two cholesteric liquid-crystal layers with different helical pitches is reported, displaying the optical diode performance: that is, the non-reciprocal transmission of circular polarized light at the photonic-bandgap regions.
Journal ArticleDOI
Thresholdless antiferroelectricity in liquid crystals and its application to displays
Shiroh Inui,Iimura Noriko,Tsuyoshi Suzuki,Hiroshi Iwane,Kouichi Miyachi,Yoichi Takanishi,Atsuo Fukuda +6 more
TL;DR: A simplified model of the phase with this property is presented in this article, which shows V-shaped switching, realizing attractive display characteristics: extremely wide viewing angle with very large contrast ratio, high speed response and ideal analogue grey scale with no hysteresis.
Journal ArticleDOI
Origin of Helix in Achiral Banana-Shaped Molecular Systems
Tomoko Sekine,Teruki Niori,Masato Sone,Junji Watanabe,Suk-Won Choi,Yoichi Takanishi,Hideo Takezoe +6 more
TL;DR: The origin of the helix is discussed in view of the twisted molecular conformation (conformational chirality) and the escape from macroscopic polarization in this paper.
