Abstract
The non-activated spiropyran dye 6-(p-chlorophenylazo) -1',3',3'-trimethyls piro[2H-1-benzopyran-2,2'-indolin] (2) was synthesized and resolved by chir al stationary phase HPLC. The chiroptical properties of the optically activ e dye were determined by circular dichroism spectropolarimetry. (C) 1998 El sevier Science Ltd. All rights reserved.
