Photoswitched DNA-Binding of a Photochromic Spiropyran [PDF]

Journal of the American Chemical Society, 2008
The dramatically different DNA-binding properties of the two isomeric forms of a photochromic spiropyran have been demonstrated, enabling photoswitched DNA binding. The closed, UV-absorbing form shows no signs of interaction with DNA. Upon UV exposure the spiropyran is isomerized to the open form that binds to DNA by intercalation. The process is fully

Spiropyran Photoisomerization Dynamics in Multiresponsive Hydrogels

Journal of the American Chemical Society, 2021
Light-responsive, spiropyran-functionalized hydrogels have been used to create reversibly photoactuated structures for applications ranging from microfluidics to nonlinear optics. Tailoring a spiropyran-functionalized hydrogel system for a particular application requires an understanding of how co-monomer composition affects the switching dynamics of ...
