Cyclodextrin modified with dansyl

Cyclodextrins modified with dansyl (5-dimethylamino-l-naphthalenesulfonyl) fluorophore were used by us for generating enantioselective fluorescence response...

Armstrong and co-workers [466] studied the retention of the DL isomers of dansyl-substituted amino acids on both (R)- and (5)-(naphthylethyl)carbamoyl-modified -cyclodextrin column. The A and a values for nine amino acids with a wide range of substituents added to the terminal amine group were tabulated. The mobile phase compositions used were analyte-dependent but ranged fiom 99/1 ethanol/acetic acid to 25/75 ethanol/acetonitrile (-H% acetic acid) with a 50/50 ethanol/acetonitrile (-1-1% acetic acid) composition being most fi-equently used. 

Lepri et al. (114-117) investigated the chromatographic behavior of dansyl-, dinitrophenyl and P-naphthyl-substituted amino acids, and alkaloids on layers of partially CIS-modified silica with aqueous-organic solutions containing P-cyclodextrin as chiral agent. Also the influence of the concentration of urea in the eluent was studied.
