✦ Synopsis

Emission spectra of pN,Ndimethylamino benzonitrile (DMABN) in aqueous &cyclodextrine @CD) solutions are reported, In ECD 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 B-CD cavity while the latter is due to DMABN molecules only partially enclosed in the cavity.

The absorption and emission of 4-(N,N-dimethylarnino)benzonitrile (DMABN) in a-cyclodextrine (a-CD) cavities is reported. The twisted intramolecular charge transfer emission is enhanced on complexation with a-CD. This is attributed to the reduced polarity of the CD environment.

Dual fluorescence of 4dimethylaminobenzonitrile (DMABN) has been used to study the behavior of DMABN in a-cyclodextrine (a-CD). Results obtained indicate that DMABN in an aqueous a-CD solution probably exists in three different environmental conditions; polar, slightly polar and hydrophobic. DMABN s
