Abstract
The Back Cover picture displays that fast and efficient switching of a photochromic oxazine can be performed at low laser powers with excellent fatigue resistance if a methoxy substituent is introduced on the chromophore responsible for absorbing the activating photons. More information can be found in the Full Paper by F. M. Raymo and co‐workers on page 1852 in Issue 12, 2016 (DOI:10.1002/cphc.201600141).
