Three photochromic indoline spirochromenes that contain styryl-substituents in the 5 position of the indoline part of the molecule were synthesized. The introduction of a styryl substituent into this position gives rise to a 15–20 nm bathochromic s

A number of photochromic 1-carbethoxymethyl-3,3-dimethyl-6′-nitroindoline-2-spiro-2′-2H-chromenes were synthesized. The introduction of a carbethoxymethyl substituent at the nitrogen atom instead of a methyl group somewhat increases the rate of d

A number of photochromic indoline spirochromenes with benzyl, acetonyl, and ethyl substituents attached to the nitrogen atom in the indoline part of the molecule were synthesized. The introduction of a benzyl group at the nitrogen atom in place of a

The introduction of aryl substituents in the 3′ and 7 positions of the indoline spirochromene molecule gives rise to a certain amount of slowing down of dark decolorization in toluene and dioxane; similar changes in the 5′, 6, and 8 positions do

Photochromic spirochromenes that differ from the standard indoline spirochromenes with respect to an angularly annelated pyridine ring were synthesized from 8-hydrazinoquinoline. The spectral characteristics of the merocyanine form of the compounds p
