Reversible modulation of the fluorescence of pyrenemethylamine hydrochloride by light in the presence of spiropyran: signal communication between two molecular switches through proton transfer

The fluorescence of pyrenemethylamine hydrochloride was reversibly modulated by light in the presence of spiropyran. The results demonstrated the signal communication through proton transfer between one three-state molecular switch based on spiropyran and one fluorescence molecular switch.
