Liquid crystalline amorphous blue phase and its large electrooptical Kerr effect
An amorphous blue phase III with low and wide thermal range (∼20 °C) including room temperature is induced by doping a bent-core nematic with a strong chiral material. We confirm that theExpand
Enhancement of Light Extraction from Organic Light-Emitting Diodes with Two-Dimensional Hexagonally Nanoimprinted Periodic Structures Using Sequential Surface Relief Grating
Electric characteristics of organic light-emitting diodes (OLEDs) with two-dimensional hexagonally nanoimprinted periodic structures were investigated, and enhanced light extraction from this deviceExpand
Light extraction from organic light-emitting diodes enhanced by spontaneously formed buckles
Organic light-emitting diodes featuring layers with a spontaneously formed buckled geometry are demonstrated to offer at least a twofold improvement in light extraction efficiency across the entireExpand
How doping a cholesteric liquid crystal with polymeric dye improves an order parameter and makes possible low threshold lasing
Lasing conditions in a dye-doped cholesteric liquid crystal (ChLC) have been studied in view of optical modes for the light propagating in ChLCs using a polymeric dye with the transition dipoleExpand
Topology-dependent self-structure mediation and efficient energy conversion in heat-flux-driven rotors of cholesteric droplets
When heat flux is applied to a chiral liquid crystal, unidirectional rotation is induced around the flux axis, as first discovered by Otto Lehmann in 1900. In recent years, this heat-flux-inducedExpand
Enhanced optical activity by achiral rod-like molecules nanosegregated in the B4 structure of achiral bent-core molecules.
Chirality in a mixture system consisting of bent-core 1,3-phenylene bis[4-(4-8-alkoxyphenyliminomethyl)benzoates] (P8-O-PIMB) and rod-like n-pentyl-cyanobiphenyl (5CB) molecules has been studied.Expand
Chiral Superstructure Mesophases of Achiral Bent-Shaped Molecules - Hierarchical Chirality Amplification and Physical Properties.
Chiral mesophases in achiral bent-shaped molecules have attracted particular attention since their discovery in the middle 1990s, not only because of their homochirality and polarity, but also due toExpand
Spontaneous deracemization of disc-like molecules in the columnar phase.
A racemic layer structure in a chiral bent-core ferroelectric liquid crystal
A fluid smectic phase of a chiral bent-core liquid crystal was found to have a ground state structure that is anticlinic in tilt and ferroelectric in polar order, SmCAPF*. The layer chirality of thisExpand
Enhancement of normally directed light outcoupling from organic light-emitting diodes using nanoimprinted low-refractive-index layer
The authors have demonstrated increased light outcoupling from organic light-emitting diodes (OLEDs) based on nanoimprinted amorphous fluoropolymer, poly[perfluoro(4-vinyloxy-l-butene)] (PPFVB).Expand
