Let¡¯s face it, organic chemistry can seem difficult to learn, Safety of 1,4-Dimethoxybenzene, Especially from a beginner¡¯s point of view. Like 150-78-7, Name is 1,4-Dimethoxybenzene, molecular formula is ethers-buliding-blocks, belongs to ethers-buliding-blocks compound. In a document, author is Arakawa, Yuki, introducing its new discovery.
Carbonyl- and thioether-linked cyanobiphenyl-based liquid crystal dimers exhibiting twist-bend nematic phases
A homologous series of ketone-type liquid crystal (LC) dimers, namely carbonyl- and thioether-linked cyanobiphenyl-based bent LC dimers (CBCOnSCB), with odd numbers of alkylene spacers (n = 3, 5, 7, and 9), was developed. CBCOnSCB dimers (n = 3, 5, and 7) formed a twist-bend nematic (N-TB) phase below the nematic (N) phase. The N to N-TB phase-transition temperatures of CBCOnSCB were higher than those of previously reported symmetric bis(thioether)-linked CBSnSCB and asymmetric ether- and thioether-linked CBOnSCB analogs. Compared to the vitrifiable CBSnSCB and CBOnSCB analogs, CBCOnSCB tended to crystallize. Single-crystal X-ray structural analysis of CBCO5SCB was also performed. (C) 2020 Elsevier Ltd.
