Abstract(s)Synthesis of new benzo[a]phenoxazinium chlorides possessing the (4,6-dichloro-1,3,5- triazin-2-yl)amino at 5-amino function of the heterocycles is described. The preliminary photophysical properties of these compounds in anhydrous ethanol when acidified with TFA or basified with TEAH is also investigated, as well as their response in aqueous media. These benzo[a]phenoxazinium chlorides exhibited fluorescence with maximum emission wavelengths between 628 and 676 nm, in anhydrous ethanol and water.
