Abstract: The title bisspirooxazine was synthesized by reacting 1-nitroso-2-naphthol with N,N'-1,4-butylene bis(2-methylene-3,3-dimethyl-indoline) in anhydrous ethanol.The structure of the compound was identified by IR, UV,1H NMR and elemental analysis. The photochromic behavior of the bisspiro compound also has been examined.

Key words: bisspirooxazine, photochromism
