Practical synthesis of photochromic diarylethenes in integrated flow microreactor systems

An effective method for the synthesis of photochromic diarylethenes through the generation of heteroaryllithiums and subsequent reaction with octafluorocyclopentene has been developed by using integrated flow microreactor systems. Reactions can be conducted without using cryogenic conditions by virtue of effective temperature and residence time control, although much lower temperatures (<-78C) are needed for batch macroreactions. Moreover, the synthesis of unsymmetrical diarylethenes, which is difficult to achieve when using conventional batch macrosystems, has been accomplished based on the selective introduction of one aryl group to give arylheptafluorocyclopentene followed by the introduction of another aryl group. The productivity of the laboratory-scale system is approximately 0.5 mmolmin-1. Therefore, the present integrated flow microreactor method serves as a practical way of synthesizing various photochromic diarylethene derivatives. Too successful to be cool: An effective method for the synthesis of photochromic diarylethenes has been developed by using integrated flow microreactor systems. Reactions can be conducted without the need for cryogenic conditions by using these systems (see picture). The synthesis of unsymmetrical diarylethenes, which is difficult to achieve by using conventional macro batch systems, has also been accomplished.

Regioselective copper-catalyzed chlorination and bromination of arenes with O2 as the oxidant

Electron-rich aromatic C-H bonds undergo regioselective chlorination and bromination in the presence of CuX2, LiX (X = Cl, Br) and molecular oxygen. Preliminary mechanistic insights suggest that the bromination and chlorination reactions proceed by different pathways.

Rational design of a visible-light photochromic diarylethene: a simple strategy by extending conjugation with electron donating groups

Photochromic diarylethenes have been widely used in many fields. However, their cyclization process must be induced by UV light. In this article, a simple strategy is developed by extending pi-conjugation with electron donating groups. The modified dirylethene derivative can photocyclolize under 405-nm light with a good photochromic efficiency. Meanwhile, its absorption and moderate fluorescence can be switched effectively in both directions by visible lights (405 and 520 nm, respectively) in different solutions and in living cells. We believe that this simple method will become a versatile strategy for developing various dirylethylenes with visible-light photochromism.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Synthesis of a novel family of photochromic amorphous molecular materials based on dithienylethene, their photochromic properties and application for dual image formation

A novel family of photochromic amorphous molecular materials containing a dithienylethene moiety, 1-{5-[4-(di-p-tolylamino)phenyl]-2-methylthiophen-3-yl}-2- (2,5-dimethylthiophen-3-yl)-3,3,4,4,5,5-hexafluorocyclopentene, 1-{5-[4-(di-p-tolylamino)phenyl]-2-methylthiophen-3-yl}-2- (2-methylbenzo[b]thiophen-3-yl)-3, 3,4,4,5,5-hexafluorocyclopentene and 1,2-bis{5-[4-(di-p-tolylamino)phenyl]-2-methylthiophen-3-yl}-3, 3,4,4,5,5-hexafluorocyclopentene, have been designed and synthesised. These compounds, together with their photocyclised products, were found to readily form amorphous glasses with well-defined glass transition temperatures and to undergo photochromism as amorphous films as well as in solution. These compounds are characterised by high quantum yields for the photocyclisation reactions, very low quantum yields for the reverse ring-opening reactions and, hence, almost 100% fractions of the photocyclised form at the photostationary state in solution. These results suggest that the anti-parallel conformer is more populated than the parallel conformer. Optical dichroism was induced by irradiation of coloured films of the photocyclised compounds with linearly polarised red light, and dual image formation at the same location was realised by utilising this phenomenon.

Photoswitchable “turn-on” Fluorescence Diarylethenes: Substituent Effects on Photochemical Properties and Electrochromism

A series of “turn-on” fluorescence diarylethenes derived from 2,3-bis(2-methylbenzo[b]thiophen-3-yl)-5,6-dihydro-4H-thieno[2,3-b]thiopyran-4-one (1) with alkyl and acetyl substituents were synthesized. The photochemical and photophysical properties of these derivatives, including the photoreaction of crystalline 1, were thoroughly investigated to reveal substituent effects on their properties. The results indicated that alkyl substituents did not significantly affect the absorption and emission spectra of the diarylethenes. However, large absorption and emission wavelength shifts were observed for the diarylethene with an acetyl substituent due to extension of pi-pi conjugation. Significantly, all of the fluorescent ring-closed forms of the compounds isomerized to their ring-open forms in the presence of Cu2+ in the dark. EPR results provide clear evidence for the formation of the compound 1 radical cation intermediate that might be generated in the reaction between c-1 and Cu2+. DFT calculations found that the ground-state activation energy for ring-opening of 1.+ was approximately 9.2 kcal mol-1 lower than that of 1 without Cu2+, such that a Cu2+-catalyzed oxidative cycloreversion reaction at room temperature might be possible.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 10243-15-9, help many people in the next few years.SDS of cas: 10243-15-9

Novel sulfoxide-introducing reaction and photochromic reactions of ethenylsulfinyl derivatives of dithienylethenes

New diarylethenes possessing one or two arenesulfinylethenyl moieties were casually synthesised.

While its colouring quantum yield by 313-nm irradiation (PhiO?C) was as large as 0.46, its bleaching quantum yield by 621-nm irradiation (PhiO?C) was negligibly small. Diels-Alder reaction of 2-(4-toluenesulfinyl)-1,4-benzoquinone with diarylethenes with the structure of 1-aryl-2-(5-ethenyl-2-methyl-3-thienyl)-3,3,4,4,5, 5-hexafluorocyclopentene gave, instead of the expected Diels-Alder cycloadduct or its derivatives, 1-aryl-2-{2-methyl-5- [2-(4-toluenesulfinyl)ethenyl]-3-thienyl}-3,3,4,4,5, 5-hexafluorocyclopentene.
