Thumbnail image of graphical abstract

A new method for fluorescence imaging based on a polymeric photobase generator containing oxime-urethane groups was developed via the use of fluorescamine, a prefluorescent amino-group dye. The fluorescent image obtained is stable and has a high contrast and good resolution (see Figure). In addition, it is possible that the fluorescent image can be erased or restored by the alternative treatment of base and acid.
