Usage

General Description

P-Ethyynyloctylbenzene is a chemical compound that belongs to the family of alkynes, which are saturated hydrocarbons containing carbon-carbon triple bonds. It is commonly used as a starting material for the synthesis of other organic compounds, such as pharmaceuticals, polymers, and agrochemicals. P-Ethyynyloctylbenzene is also used as a building block in the production of specialty chemicals and in research applications. It is a colorless liquid with a mild, aromatic odor and is typically stored and handled under controlled conditions due to its flammability and potential hazards.

Synthesis and Physical Properties of Asymmetric Diphenyldiacetylenic Liquid Crystals

Fifty-six asymmetric diphenyl-diacetylene liquid crystal homologs including dialkyl, alkyl-alkoxy, cyano-alkyl, chloro-alkyl, fluoro-alkyl, difluoro-alkyl, lateral chloro-substituted fluoro-alkyl (or alkoxy), lateral fluoro-substituted asymmetric dialkyl, and vinyl-alkyl are synthesized and their physical properties evaluated.Among these asymmetric diphenyl-diacetylene liquid crystals, many dialkyl homologs exhibit low melting point, wide nematic range, and low heat of fusion.They are ideal host candidates for formulating eutectic mixtures.The polar groups make important contributions to the phase transition temperature, dielectric anisotropy, refractive indices and viscosity.Detailed effects depend on the position of the substitution.These new liquid-crystals compounds and mixtures are particularly useful for electro-optic modulation of infrared radiation. - Keywords: Diphenyl-diacetylenes, eutectic mixtures, electro-optic modulation, physical properties
