Abstract
Emission spectra of p-N,N-dimethylamino benzonitrile (DMABN) in aqueous β -cyclodextrine (β -CD) solutions are reported. In β -CD two distinct kinds of emission are observed, one with enhanced nonpolar emission (at 355 nm) and the other exhibiting enhanced TICT emission (at 480 nm). The former is attributed to those DMABN molecules which are totally inside the β -CD cavity while the latter is due to DMABN molecules only partially enclosed in the cavity.
