New photochromic phenyl-substituted polyphenylenes containing azobenzene fragments in the backbone have been synthesized by the interaction of diacetylenes with bis(cyclopentadienones) via the Diels-Alder reaction. The polymers thus prepared exhibit the photochromic behavior and combine solubility in common organic solvents with high viscosity and thermal characteristics. 相似文献

Nitro-substituted benzothienopyrroline spiropyrans containing substituents in the ben-zothienopyrroline moiety were synthesized.
The comparative spectral kinetic study of the pho-tochromic transformations of these compounds and their indoline analogs
in solvents of various polarity was carried out. On the basis of the results obtained and literature data, the photoin-duced
aggregation of molecules of the merocyanine form in weakly polar solvents was suggested. 相似文献

The photochromic properties and aggregation processes of merocyanine forms of indoline spiropyrans of the coumarin series
in the block and film poly(methyl methacrylate) (PMMA) were studied and compared by spectral and kinetic methods. Photochromism
of the synthesized compounds depends on their structure. The efficient formation of J-aggregates was observed for indoline
spiropyrans of the coumarin series based on 8-formyl-7-hydroxy-4-methylcoumarin and 3-formyl-4-hydroxycoumarin.

The photochromic properties and aggregation processes of merocyanine forms of indoline spiropyrans of the coumarin series
in solutions were studied by spectral and kinetic methods. Photochromism of the compounds synthesized depends on their structure.
The efficient formation of J-aggregates was found for indoline spiropyrans 1a,b under UV irradiation and merocyanines 3a,b, which is indicated by the appearance of absorption and fluorescence bands in the visible spectral region and the resonance
character of fluorescence.

For the first time 5,7-di-tert-butyl-1,3-dimethyl-3a,9a-diphenyl-3,3a-dihydro-1H-benzo[5,6][1,4]dioxino[2,3-d]imidazol-2(9aH)-one 13 and complex 9 of 4,6-di-tert-butyl-3-nitrobenzene-1,2-diol with 1,3-dimethyl-4,5-diphenyl-1H-imidazol-2(3H)-one 10a were prepared by the reactions of 3-alkylthio-5,7-dimethyl-4a,7a-diphenyl-4a,5,7,7a-tetrahydro-1H-imidazo[4,5-e]-1,2,4-triazin-6(4H)-ones with 3,5-di-tert-butyl-1,2-benzoquinone 1 and 4,6-di-tert-butyl-3-nitro-1,2-benzoquinone 2, respectively. Photochemical transformations of compounds 9 and 10a as well as products of its photooxygenation involving singlet oxygen under UV irradiation: urea 16, isomeric 1,3-dimethyl-4,5-diphenylimidazolidin-2-ones 17 and 17′, and compound 18 were studied by the spectral-kinetic method. Data on the absorption and fluorescence properties of synthesized compounds and their photoproducts were obtained. 相似文献

A functionalization of the surface of detonation nanodiamonds by photochromic spirocompounds from the classes of spiropyrans and spirooxazines has been carried out for the first time. A comparative study of the interaction of nanodiamonds with positive and negative potential is performed by the spectral–kinetic method, which shows the possibility of surface modification by only functionalized molecules of spirocompounds with the formation of surface proton complexes. This is confirmed by the hypsochromic shift of the absorption bands of the photoinduced merocyanine forms of adsorbed molecules of spirocompounds and by the decrease of the speed of their dark relaxation to the initial state in the presence of nanodiamonds with a negative potential. 相似文献
