Abstract
The induced circular dichroism (i.c.d.) and absorption spectra of the β-cyclodextrin (β-c.d.) complex with cyclobuta [1,2-b: 3,4-b′]diquinoxaline (I) have been measured. The linear dichroism (l.d.) spectra of I in stretched polyethylene sheet have been also measured. The absorption bands of I have been assigned by using the observed spectra and the results of CNDO/S CI calculations. The i.c.d. spectra of the first absorption band have shown the Cotton-effect at high concentrations. This fact indicates that the β-c.d. complex with I forms dimers at high concentrations.
