Reversing the Thermal Stability of a Molecular Switch on a Gold Surface: Ring-Opening Reaction of Nitrospiropyran

Autor: Martin Wolf, Alex Krüger, J. Miguel, Gunnar Schulze, Matthias Koch, Felix Leyssner, Petra Tegeder, Jose Ignacio Pascual, Cristina Navío, Wolfgang Kuch, Matthias Bernien, Katharina J. Franke, Marten Piantek

Publikováno v: Journal of the American Chemical Society. 131:12729-12735

The ring-opening/closing reaction between spiropyran (SP) and merocyanine (MC) is a prototypical thermally and optically induced reversible reaction. However, MC molecules in solution are thermodynamically unstable at room temperature and thus return
