title: Design and synthesis of a novel fluorescence probe for Zn2+ based on the spirolactam ring-opening process of rhodamine derivatives.
abstract: 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 Zn(2+) sensor, and successfully developed a new fluorescence probe for Zn(2+).
