Dendrimers with azo moieties in their peripherals (azodendrimers), which we developed, are useful as a photoactive interface for liquid crystal (LC) systems. The azodendrimer spontaneously adsorbs on a variety of interfaces, so that we can obtain pho

Current approaches to demonstrate light-driven writing enabling multiple “write–erase” cycles are mostly based on photochromic materials requiring complex synthesis processes. Here, we show a new approach to realize rewritable, light-driven rec

Brief overview of polar liquid crystals (LCs) is given with a tutorial manner. They are chiral smectic C ferroelectric LCs (FLCs), chiral smectic CA antiferroelectric LCs (AFLCs), their ferrielectric subphase LCs, chiral columnar FLCs, chiral and non

We systematically studied the photoinduced anchoring transition in a nematic liquid crystal containing azo dendrimers. Because the azo dendrimers in the trans-isomer state were spontaneously adsorbed at substrate surfaces, which was confirmed by opti

In this work, we prepared a series of nonchiral bent-core molecules with different terminal alkoxy chain lengths, and measured the helical twisting power (HTP) of the bent-core molecules doped in a chiral nematic liquid crystal (N*LC). We investigate

The alignment of nematic liquid crystal 5CB in micron-thick shells, suspended in and containing aqueous liquid phases, can be rapidly switched between radial (homeotropic) and tangential (planar) director field by doping them with a photoresponsive d

Color conversion, long-wavelength light emission by absorbing short-wavelength light, is an attractive approach for developing a broad-color expression technology and is widely used in solid-state lighting, dye-lasers, and colorful displays. Up to no

We demonstrate circular flow formation at a surface in homeotropically oriented nematic liquid crystals with a free surface using focused laser beam irradiation. Under a weak laser power, a pit together with an associated circular bulge is formed: th

We found possible chirality enhancement and reduction in chiral domains formed by photoresponsive W-shaped molecules by irradiation with circularly polarized light (CPL). The W-shaped molecules exhibit a unique smectic phase with spontaneously segreg
