Conclusions

An x-ray diffraction structural analysis of photochromic 1'-3',3'-trimethyl-6-nitro-8-bromospiro (4-azaindoline-2,2'-t2H-l]benzopyran) showed that azaindoline and indoline spiropryans have similar structures, in which the Cspiro-O bond cleaved upon photoexcitation is elongated and weakened.
