Usage

General Description

5-Methyl-4-nitro-o-anisidine, also known as MNMA, is a chemical compound that consists of a nitro group, a methoxy group, and a methyl group attached to a benzene ring. It is commonly used as an intermediate in the production of dyes and pigments. MNMA is a yellow crystalline solid at room temperature and is slightly soluble in water. It is known to be harmful if swallowed, inhaled, or if it comes into contact with the skin, and may cause irritation to the respiratory system and skin. Due to its potential health hazards, proper safety measures should be taken when handling this chemical.

Compounds and methods for doping liquid crystal hosts

This invention provides chiral thioindigo compounds for doping smectic liquid crystal hosts, wherein the compounds modulate a chiral bulk property of an induced chiral smectic liquid crystal phase upon irradiation at a wavelength in the visible range. Modulation of the chiral bulk property is effected by reversible trans-cis photoisomerization of the compound upon irradiation. The compounds maintain their rod-like shape in both isomeric forms, and hence do not destabilize the chiral smectic liquid crystal phase. Compounds according to the invention are useful in optical devices such as optical switches, displays, and memory.
