Azobenzene photochemistry is a fascinating area of investigation, on one hand, because it
is fairly wellknown, 1 and on the other hand because it has produced and continues to …

The history of human civilization is accompanied by the development of novel materials,
from the period of natural stone, the bronze and iron age, to the modern times of synthetic …

Two types of photomodulation of orientations of liquid crystals (LCs) are reviewed: 1) order–
disorder phase transitions of LCs induced by photochemical reactions of photochromic …

Being one of the most fascinating multi-functional materials, photoresponsive liquid
crystalline block copolymers (PLCBCs) have attracted much attention because of their light …

We report on the fast and optically controlled angular bending of cantilevers made from
liquid crystal polymer networks functionalized with azobenzene moieties (azo-LCN). For …

Reversion of the in-plane reorientation direction of mesogenic groups has been observed
for the first time in novel polymethacrylate liquid crystal (PLC) films substituted with a 4 …

Recent progress in alignment modulation of azobenzene-containing liquid crystal systems
by photochemical reactions has been reviewed by dividing the modulation methods into two …

The following article is a tribute to the late Almeria Natansohn and is based on a brief
summary of her research in azopolymers. She showed that reversible trans–cis–trans …

We have carried out two-beam interference experiments to form surface-relief gratings
(SRGs) on azo polymer films under different polarization combinations. The mechanism of …

In this article, we describe the fabrication of azobenzene-containing supramolecular side-
chain polymer films based on hydrogen bonds, on which surface relief gratings can be laser …
