Usage

General Description

Phenol, p-((p-Methoxyphenyl)azo)-, also known as p-Anisaldehyde azophenol, is an organic compound commonly used as an indicator in analytical chemistry. It is a yellow to dark red powder that is soluble in organic solvents but insoluble in water. This chemical is commonly used for the determination of aluminium, beryllium, and boron. It forms a red complex with aluminium ions in a slightly acid solution, making it a useful reagent for the spectrophotometric determination of aluminium. Additionally, it has also been used in the development of a sensitive and selective flow injection analysis system for the determination of beryllium. Due to its potential as an environmental pollutant, the use and handling of Phenol, p-((p-Methoxyphenyl)azo)- should be carefully managed to minimize any adverse effects on human health and the environment.

Low-temperature nematic phase in azo functionalised reactive hockey stick mesogens possessing lateral methyl group

We report, the design, synthesis and mesomorphic behaviour of new hockey stick mesogens containing photochromic azo group and a reactive double bond. The structure of the compounds resemble the hockey stick due to unequal distribution of the phenyl rings

The role of conductivity and molecular mobility on the photoanisotropic response of a new azo-polymer containing sulfonic groups

We report the preparation of a new light-responsive side-chain terpolymer containing azobenzenes, as chromophoric components, sulfonic groups, as polar components, and methacrylate groups, as film forming components, and we provide a detailed characterisa

Thermostable birefringent copolyimide films based on azobenzene-containing pyrimidine diamines

Azobenzene (azo)-containing polymers have attracted continuous attention due to their excellent photosensitivity. However, practical applications of their photo-induced birefringence have been hampered by low thermal stability. In this work, we report a s
