3-(5-ALKOXY-1,2-DIMETHYL-1H-INDOLE-3-YL)-4-[(1E)-ALK-1-ENYL]FURAN-2,5-DIONES AND THEIR USING AS FLUORESCENT PHOTOCHROMES Russian patent published in 2008 - IPC C07D405/04 C09K11/06

Abstract RU 2314304 C1

FIELD: organic chemistry.

SUBSTANCE: invention relates to novel 3-(5-alkoxy-1,2-dimethyl-1H-indole-3-yl)-4-[(1E)-alk-1-enyl]furan-2,5-diones of the general formula (I): wherein R₁ means (C₁-C₆)-alkyl; R₂ means (C₁-C₆)-alkyl. Compounds of the formula (I) elicit photochrome and fluorescent properties. Also, invention relates to using 3-(5-alkoxy-1,2-dimethyl-1H-indole-3-yl)-4-[(1E)-alk-1-enyl]furan-2,5-diones of the general formula (I) as fluorescent photochromes that can be used, for example, in systems for storage and treatment of information, in particular, as photosensitive component of materials for three-dimensional recording and storage of information, and can be used in the design of elemental base for molecular computers also, in particular, as molecular switches.

EFFECT: valuable technical properties of compounds.
