title: From slow to fast--the user controls the rate of the release of molecules from masked forms using a photoswitch and different types of light.
abstract: Exposure to UV light generates a ring-closed isomer of a diarylethene, which undergoes very slow bond breaking and release even after the light is turned off. The rate of release is increased by exposing the isomer to UV and/or visible light.
