Abstract
9-Anthrylethylene derivatives 1 to 12 are synthesized to study their f luorescence properties. Dual emission is observed in some cases and it s origin is due to involvement of locally excited (LE) and charge tran sfer (CT) excited states. Fluorescence solvatochromism observed is a c lear indication for the involvement of CT state. Photochemical trans-c is isomerisation originates from the CT singlet excited state. Effects of solvent polarity, solvent viscosity, acceptor group and micellar e ffects on fluorescence of these 1-12 were also studied. Copyright (C) 1997 Elsevier Science Ltd.
