Abstract
A new family of biomimetic photoactivated molecular switches based in the retinal chromophore is described. Expedient synthesis allows a library of compounds with a different substitution pattern, including chiral substituents, to be obtained. The effect of substitution, solvent, and light source on thephotoisomerization step has been assessed. The absorption maximum has been red-shifted ca. 50 nmwith respect to related systems and rotation is now easily achieved by using visible light.
