Usage

General Description

1,3,6,8-Tetrachloropyrene is a chemical compound that belongs to the family of polycyclic aromatic hydrocarbons (PAHs). It is a highly toxic and mutagenic pollutant that is formed during the incomplete combustion of organic matter, such as fossil fuels, wood, and tobacco. It has been identified as a potential human carcinogen and is known to be harmful to aquatic life. 1,3,6,8-Tetrachloropyrene has been found in various environmental matrices, including air, water, and soil, and poses a significant risk to human health and the environment. Efforts to control and reduce the release of this chemical into the environment are essential to minimize its impact on public health and ecosystems.

Synthesis and phase structures of novel π-acceptor discotic liquid crystalline compounds having a pyrenedione core

Several π-acceptor discotic liquid crystalline compounds were synthesized by using a pyrenedione unit as a core. Terrace-like and band-like structures were revealed by polarized optical microscopy (POM) observations and XRD measurements. In conjunction with the results of the single-crystal structure analysis of analogous crystalline compounds, all of the liquid crystalline compounds were confirmed to form a discotic lamellar phase D L2.
