The front cover artwork is provided by Massimo Baroncini. The image depicts a phenomenon known as inner filter effect, in which the light emitted in solution by 8‐methoxyquinoline in its basic form is reabsorbed by the acid form of the same fluorophore. The combination of inner filtering with acid–base switching leads to a nonlinear input–output response. Read the full text of the article at 10.1002/cphc.201700046.
