WebIn this Concept Article, we analyze known helicene systems that function as chiroptical photoswitches from a stereochemical perspective and classify them based on the type of transformation of the helicene core that takes place during the switching process. In every case, we inspect the stereodynamics of each of the two forms of the switch and ... WebMar 27, 2015 · Nucleic acids that change their properties upon photo-irradiation could be powerful materials for molecular sensing with high spatiotemporal resolution. Recently, we reported a photo-isomeric nucleoside bearing azobenzene at the C5 position of 2'-deoxyuridine (dUAz), whose hybridization ability could be reversibly controlled by the …
