The spirolactam ring-opening process of rhodamine derivative is one of the most useful mechanisms for controlling fluorescence properties. However, the open/closed equilibrium reaction of rhodamine spirolactam has not been well characterized. Therefore, we examined the relationship between the spirolactam ring-opening process of rhodamine derivatives and the structure of the xanthene moiety. Based on the results of this investigation, we selected a candidate xanthene moiety for a Zn2+ sensor, and successfully developed a new fluorescence probe for Zn2+. (C) 2010 Elsevier Ltd.
