Spiropyrans of the 2-oxaindan series with 2H-chromene fragments benzo-and 2,3naphthoannelated at the 7-8 bond were synthesized. The molecular structures of four of the spiropyrans obtained were determined by x-ray diffraction studies, and their photo-and thermochromic properties were studied. Annela
