Abstract In the previous study, the existence of an unidentified ferroelectric smectic phase is demonstrated in the low‐temperature region of the ferroelectric smectic A phase, where the layer spacing decreases with decreasing temperature. In the p

Abstract Polymer‐dispersed liquid crystals (PDLCs) with nano‐phase‐separated structures, in which nanometer‐sized liquid crystal (LC) domains are dispersed within a polymer matrix (nano‐PDLCs), are transparent solid materials whose optical

Nanostructured polymer-dispersed liquid crystals (nano-PDLCs) are transparent and optically isotropic materials in which submicron-sized liquid crystal (LC) domains are dispersed within a polymer matrix. Nano-PDLCs can induce birefringence by applyin

Abstract Ferroelectricity in fluid materials, which allows free rotation of molecules, is an unusual phenomenon raising cutting‐edge questions in science. Conventional ferroelectric liquid crystals have been found in phases with low symmetry that p

The introduction of electron-withdrawing groups such as CN and NO2 groups at the end position of C3-DIO analogues increases the dipole moments above 8.5 D, which is effective method for the emergence of ferroelectric nematic phases in C3-DIO series.

Polyethyleneimine (PEI) complexed with chiral D- (or L-) tartaric acid (tart) in water can self-organize into chiral and crystalline PEI/tart assemblies. It has been previously confirmed that the complexes of PEI/tart could work as catalytic/chiral t
