Abstract: A novel bisazomethine Schiff base was synthesised by the condensation of 3-hydroxyquinoxaline-2- carboxaldehyde and 2,3-diaminomaleonitrile. 1H NMR, 13C NMR, HPLC and FT-IR studies revealed that the compound exists in two major tautomeric forms. The Schiff base exhibits positive absorption and fluorescent solvatochromism and displays dual fluorescence with large stoke shifts. Cyclic voltammetric analysis of the compound in 1:1 methanol–THF was influenced by scan rate. Thermal analysis of the compound was undertaken using TG–DTA and DSC
