Sensitizers) 2,3,3-Trimethylindolenine (I) was treated with squaric acid (II) in the presence of H2SO4 to give 1,3-bis(3,3-dimethyl-2-methyleneindolenine)squarylium cyanine dye (III). Treatment of I with 1,3-propane sultone followed by reaction with II gave 1,3-bis[N-(3-sulfonylpropyl)-3,3-dimethyl-2-methyleneindolenine]squaryli um cyanine dye. The crystal structure of III was determine by x-ray diffraction method.
