Synthesis of photochromic diarylethenes using a microflow system.
An effective method for the synthesis of photochromic diarylethenes based on microflow systems has been developed, and the synthesis of unsymmetrical diarylethenes which is difficult to achieve using conventional macro batch systems, has been accomplished.
متن کاملThe effect of the formyl group position upon asymmetric isomeric diarylethenes bearing a naphthalene moiety
Three new isomeric asymmetric diarylethenes with a naphthyl moiety and a formyl group at the para, meta or ortho position of the terminal benzene ring were synthesized. Their photochromism, fluorescent-switch, and electrochemical properties were investigated. Among these diarylethenes, the one with a formyl group at the ortho position of benzene displayed the largest molar absorption coefficien...
متن کاملThe isolation and photochemistry of individual atropisomers of photochromic diarylethenes.
All three atropisomers of photochromic diarylethenes were isolated for the first time and the stereospecific photochemical switching process studied by UV-vis and CD spectroscopy.
متن کاملEffects of Photochromic Furan-Based Diarylethenes on Gold Nanoparticles Aggregation
The photochromic properties of furan-based diarylethenes and their interaction with citrate-capped gold nanoparticles were investigated by ultraviolet/visible absorption spectroscopy and transmission electron microscopy. We identified the optimal concentration of diarylethenes in water-ethanol mixture required for stability of colloidal systems. Nanoparticles coupled with diarylethene derivativ...
