Photorelease of HCl from o-Methylphenacyl Chloride Proceeds through the Z-Xylylenol

, which is the only photoenol formed in this solvent. The E-isomer is not formed, and the triplet pathway does not compete measurably. In benzene solution both the E- and Z-photoenols are formed, but only the E...

Azomethine phthalimides fluorescent E -> Z photoswitches

Herein, we report the synthesis and E -> Z photoswitching behavior of two 4 photoswitches with dual fluorescence properties as E-isomers and at photostationary state on the environmental polarity. The kinetics of <...

Z-E photoisomerisation of styrene- and stilbene-derived push-pull systems bearing 4,5-dicyanoimidazole unit.

Z-E isomerisation of six styrene- and stilbene-derived chromophores featuring 4,5-dicyanoimidazole unit was investigated. The photo-isomerisation was induced spectroscopy. It was found that the absorbance of the longest-wavelength b...

Two New Isomers of Palmityl-4-hydroxycinnamate from Flowers of Taraxacum Species

Two isomers, (Z)- and (E)-palmityl 4-hydroxycinnamate [hexadecyl(2Z)-3-(4-hydroxyphenyl)prop-2-enoate and hexadecyl(2E)-3-(4-hydroxyphenyl)prop-2- enoate] were isolated for the first time from ligulate flowers of Taraxacum ...

Acceptor-induced photoisomerization in small thienothiophene push-pull chromophores

LED afforded a dynamic equilibrium of E and Z isomers, the Z-isomer is fully. A reversible E-Z photoisomerization has been observed for the chromophores with particular isomers ...

Convenient synthesis of 3-fluoro-4,5-diphenylfuran-2(5H)-one from benzoin ethers. Novel and efficient Z-E isomerisation and cyclisation of 2-fluoroalkenoate precursors, substitution of vinylic

Mixtures of ethyl (E)- and (Z)-4-alkoxy-2-fluoro-3,4-diphenylbut-2-enoates (6-8 bromine in tetrachloromethane at room temperature. The non-cyclisable Z-isomers 6b-8b were gradually isomerised to the cyclisable ...

Transforming hemithioindigo from a two-way to a one-way molecular photoswitch by isolation in the gas phase

. Comparison between the Z and E isomers shows a quite distinctive behavior upon visible light absorption. The Z isomer readily undergoes Z -> E conversion in the gas (He-IRPD) spectra...
