How do donor and acceptor substituents change the photophysical and photochemical behavior of dithienylethenes? The search for a water-soluble visible-light photoswitch
Sili Qiu, Andrew T. Frawley, Kathryn G. Leslie, Harry L. Anderson- General Chemistry
A systematic investigation of a family of photo-switches with electron-donating and -accepting substituents reveals that the switch with two electron-accepting 4-ethynyl-pyridinium groups exhibits excellent switching behavior in aqueous solution.
