Application

(±)-1,1′-Bi(2-naphthol) was used to develop chiral fluorescent sensors for highly enantioselective detection of chiral amino alcohols, α-hydroxycarboxylic acids and amino acid derivatives. It was used in chiral separation by capillary electrophoresis using a combination of a polymerized chiral micelle and γ-cyclodextrin.

General description

(±)-1,1′-Bi(2-naphthol) forms chiral cocrystals with photochromic diarylethene having 2-methyl-4-pyridyl groups.
