Axially chiral binaphthyl derivatives with highly twisting powers were synthesised by substituting phenylcyclohexyl (PCH) mesogenic moieties into 2,2′ positions or 2,2′,6,6′ positions of binaphthyl rings. The di‐ and tetra‐substituted binaphthyl derivatives were adopted as chiral dopants to ...
Optically active axially dissymmetricbinaphthyl derivativeshave been extensively used as excellent chiral ligands in asymmetric catalysis and chiral recognition. 光学活性的联萘衍生物以其独特的立体化学性质作为优异的C2 轴手性诱导源,已被广泛地应用到不对称催化反应和手性识别中。

The (S)-enantiomers of binaphthyl derivatives such as 1,1′-bi-2-naphthol, 2,2′-dimethoxy-1,1′-binaphthyl, and 1,1′-binapthyl-2,2′-diyl hydrogen phosphate are more preferable guests for permethylated β-cyclodextrin compared with the... K Kano,K Yoshiyasu,S Hashimoto - 《Journal of...
Three novel deep blue-emitting materials from binaphthyl derivatives, namelyBFS,BNSandBNF, were designed and synthesized. Due to their rigid structure, all the materials exhibit high thermal stability with Tdexceed 440 °C and Tgas high as 153 °C, 149 °C and 140 °C, respectively. They al...
