The research and development of multi-stimuli, multi-responsive mols. have attracted considerable attention in chem., biol., and material science. Herein, the authors propose a multi-stimuli-responsive multi-fluorescence system in a single mol. This system is based on the isomerization that involves ring-opening/closing reactions of spirolactones of rhodamine analogs (ABPXs), developed by the authors’ group, which can be independently controlled by light and chem. stimuli. UV light irradiation opens one of the spirolactones to give thermally stable colored isomer (Z) in solution Detailed synthetic and theor. studies reveal that the ring-opening reaction of ABPXs proceeds via the formation of a photo-induced charge separated state, followed by the recombination of the biradicals. Furthermore, the authors explore the structure-kinetic relations and demonstrate that the introduction of electron-donating substituents into the xanthene ring can tune the lifetime of the photo-generated isomer. Chem. stimulation by an acid further promotes the ring-opening reaction to give a red shifted isomer (D). These light and chem. input signals can be converted into output signals of distinct color and fluorescence. The multi-stimuli-responsive multi-color fluorescence could be distinctively expressed through the combinatorial logic gate.
