Polysaccharide-Based Chiral LC Columns

“…5. [19][20][21][22][23][24][25][26][27] Most commercialized polysaccharide-based CSPs have been prepared by coating them on silica gel. When CTA-I was coated from a solution, the CTA afforded another useful CSP (OA in Fig.…”

Synthesis, resolution and racemization study of helically twisted o-terphenyls

“…1a) to less rigid helically twisted o-terphenyl (e.g. 1b), 3 provides a useful way to gain knowledge about chiroptics of organic molecules. In order to gain further insight into the chiroptical properties of the helical o-terphenyl system, o-terphenyls 2, 3 and 4, which are structurally related to o-terphenyl 1b, were chosen for study.…”
