Direct observation of structural heterogeneity and tautomerization of single hypericin molecules
Quan Liu, Frank Wackenhut, Liangxuan Wang +6
Tautomerization is a fast chemical reaction where structures of the reactants differ only in the position of a proton and a double bond. Tautomerization often occurs in natural sub…
Hypericin: Single molecule spectroscopy of an active natural ingredient
Quan Liu, Frank Wackenhut, Otto Hauler +4
Hypericin can be found in nature in Hypericum perforatum (St. John's Wort) and has become subject of intense biochemical research. Studies report of antidepressive, antineoplastic,…
Tunable strong coupling of two adjacent optical λ/2 Fabry-Pérot microresonators
Achim Junginger, Frank Wackenhut, Alexander Stuhl +3
Optical half-wave microresonators enable to control the optical mode density around a quantum system and thus to modify the temporal emission properties. If the coupling rate excee…
