Photoelectrocatalysis to improve cycloreversion quantum yields of photochromic dithienylethene compounds.
An open and shut case: photoirradiation of the 9-mesityl-10-methylacridinium ion, which acts as a photoredox catalyst, evoked catalytic cycloreversion of the photochromic 1,2-dithienylethene (DTE) compounds with one order of magnitude enhancement in quantum yields. Mechanistic studies revealed that the back electron transfer and electron transfer from the neutral closed form of DTE compounds to...
متن کاملPhotochromism of dithienylethene single crystals having anthracene substituents.
Three dithienylethene derivatives having anthracene substituents (connected at 1-, 2- and 9-positions) were prepared. Although these three derivatives exhibit photochromic reactivity in solution, only one of the derivatives (connected at 2-position) undergoes the photochromic reaction in the crystalline phase. X-Ray crystallographic analysis and DFT calculation revealed that conformation of the...
متن کاملPhotochromic thiophenefulgides. Photokinetics of two isopropyl derivatives
For two photochromic isopropyl-thiophenefulgides a complete photokinetic analysis is given. For one compound (Sb), the partial quantum yield for the coloming process (&c= 54%) is the highest value found for thiophenefulgides. EZ-isomerisations do not play an important role. The colouringquantum yield is temperature independent down to 20 K, whereas bleaching requires little thermal activation. ...
متن کاملChemical control of the photochromic reactivity of diarylethene derivatives.
Photochemically inactive diarylethene derivatives having a N-(O-hydroxyphenyl) group underwent photochromic reaction when they were esterified by the addition of acetic anhydride.
متن کاملPhotochromic switching of the DNA helicity induced by azobenzene derivatives
The photochromic properties of azobenzene, involving conformational changes occurring upon interaction with light, provide an excellent tool to establish new ways of selective regulation applied to biosystems. We report here on the binding of two water-soluble 4-(phenylazo)benzoic acid derivatives (Azo-2N and Azo-3N) with double stranded DNA and demonstrate that the photoisomerization of Azo-3N...
