Abstract
The CD spectra of a new series of 4-substituted [2.2]paracyclophanes 1b- e have been measured down to 185 nm. Polarizability calculations within the DeVoe model satisfactorily reproduce the CD features over all the spectral range. In addition, the analysis of the complete CD spectrum allowed a phenomenological interpretation of the dependence of the sign of [α](D) on the nature of the substituents, at least for X=F, OH, I.File in questo prodotto:
