  Abstract:  New heterocyclic Schiff bases exhibiting fluorescent properties were obtained in good yields by thermal condensation of (10-alkyl)-3-formyl-10Hphenothiazine derivatives with aromatic amines. Structural characterization was based on high resolution NMR, UV-Vis and fluorescence spectroscopy. Emission maxima were situated in the range 524-588 nm showing large Stokes shifts.

Keywords: Schiff bases, formylphenothiazine, fluorescence spectroscopy.
