Abstract
6-Nitro-6′,7′-tetramethylene-substituted photochromic spirochromenes were synthesized from 5-aminotetralin. In the series of compounds thus obtained the electronic effect of the substituents in the 8 position on the dark decolorization reaction is substantially more noticeable than in the corresponding series of standard spirochromenes. The spectral characteristics of the merocyanine form of the tetramethylene-substituted spirochromenes practically coincide with the. characteristics of the analogous unsubstituted compounds.
