In this paper, direct photooxidation of benzothiazolone cyanine dye in acetonitrile was studied. The photoproducts had been identified by 1HNMR and fast atom bombardment (FAB) mass spectrometry. The results showed that the N-ethylbeiizothiazolone (Ⅰ), the ionic acid (Ⅱ), and ionic aldehyde (Ⅲ) are the principal photoproducts.
