Abstract

The absorption and emission spectral behavior of synthesized N-alkyl- bis(styryl) pyridinium bromide dye (1) has been investigated in at pH in aqueous and micellar media. From the results it is found that in ground state the dye is in neutral form whereas in excited state it is in anionic form. Localization of dye in micelle and nature of surfactant plays important role on the dissociation constant.

Keywords
