Abstract
New heterocyclic fulgides, 3-[1-(5-alkoxy-2-methylbenzo[b]furan-3-yl)ethylidene]-4-(2-propylidene)dihydro-2,5-furandiones, and fulgimides, 1-(2-dimethylaminoethyl)-3-[(5-methoxy-2-methylbenzo[b]furan-3-yl)ethylidene]-4-(2-propylidene)dihydro-2,5-pyrroledione and 1-benzyl-3-[(5-methoxy-2-methylbenzo[b]furan-3-yl)ethylidene]-4-(2-propylidene)dihydro-2,5-pyrroledione, were synthesized. Electron spectroscopy and 1H NMR spectroscopy were used to establish that all the compounds obtained have Z-configuration and exhibit photo-chromic properties with high stability to photodegradation in solutions. Cyclic photoisomers of fulgides possess fluorescent properties and thermal stability.
