2,3-Diarylmaleate salts as a versatile class of diarylethenes with a full spectrum of photoactivity in water

Abstract

There is an incessant interest in transfer of common chemical processes from organic solvents to water, which is vital for the development of bioinspired and green chemical technologies. Diarylethenes feature...

Diaryltriazolium Photoswitch: Reaching a Millisecond Cycloreversion with High Stability and NIR Absorption

“…To circumvent this issue, an extensive structural adaptation of their aryl units is required. [15][16][17][18][19] Upon UV light exposure, open DAEs undergo photochemical 6π-electrocyclization, yielding strongly colored closed DAEs due to the formation of an extended π-system. While the open isomers mainly absorb in the UV region, the closed isomers' absorption maxima (λ max ) are in the visible range typically between 500 and 650 nm (see DAEs 1-4 in Figure 1).…”
