“…It is well known that the ring opening and closing transformation of some diarylethenes can be initiated not only by UV or visible light irradiation, but also by electrochemical or chemical oxidation, such as electrochromism 55, 56. Therefore, besides their excellent photochromic performance, the electrochemical behaviors of diarylethenes were also attracted much attention 57–60. In present study, the electrochemical examinations were performed by cyclic voltammograms (CV) method under the same experimental conditions using diarylethenes 1 – 3 , respectively.…”

Three new unsymmetrical isomeric diarylethenes having a methoxyl substituent at ortho-, meta-, and para-position of the terminal benzene ring, namely 1-(2,5-dimethyl-3-thienyl)-2-[2-methyl-5-(2-methoxylphenyl)-3-thienyl]perfluorocyclopentene (1o), 1-(2,5-dimethyl-3-thienyl)-2-[2-methyl-5-(3-methoxylphenyl)-3-thienyl]perfluorocyclopentene (2o), and 1-(2,5-dimethyl-3thienyl)-2-[2-methyl-5-(4-methoxylphenyl)-3-thienyl]perfluorocyclopentene (3o), have been synthesized. The substituent position effect of methoxyl group on their properties, including photochromism and fluorescence both in hexane solution and in PMMA film, and their electrochemical properties, were investigated in detail. These diarylethenes showed good photochromism both in solution and in PMMA film. For the same photochromic diarylethene backbone, the electrondonating methoxyl substituent can effectively depress the cyclization quantum yields and increase the cycloreversion quantum yields compared to those of diarylethenes bearing chlorine atoms reported previously. Diarylethenes 1o-3o showed clear fluorescent switches by photoirradiation both in hexane and in PMMA film. In addition, cyclic voltammetry tests showed that the electron-donating methoxyl group at different position on the terminal benzene ring had a significant effect on the electrochemical properties of these isomeric diarylethenes.

“…), followed by a re-oxidation of this radical. 7 The use of electrochemistry together with light to switch between different states, so-called redox-photochromism, was recently reported, [8][9][10] in particular for diarylethenes [11][12][13] and dihydroazulene conjugates. [14][15][16] In these compounds, while ring opening is driven by light, ring closure is triggered by electrochemical oxidation.…”

Multiresponsive chromogenic systems operated by light and electrical inputs

In the framework of supramolecular chemistry, a three component system constituted by Fe 3+ /Fe 2+ , crystal violet lactone (CVL) and a spiropyran (SPI) leads to three coloured states, cyan, magenta and yellow, as well as a transparent state, each independently addressable by light and electrical input. The system profits from fine speciation Fe 3+ /Fe 2+ complexes with CVL and SPI. Redox stimulus operates the metal, leading to different coloured complexes (ionochromism), while light stimulus operates the SPI component (photochromism).
