Photostimulated luminescence, which allows energy or data to be stored and released using electromagnetic waves as both the input and output, has attracted considerable interest in the fields of biomedical and informatics technologies, but this phenomenon is mostly limited to solid inorganic materials. Here, we report photostimulated luminescence from purely organic blend films composed of electron donor, acceptor, and trap/emitter molecules. In the films, charges are accumulated as radical ions by ultraviolet light irradiation and then extracted by near infrared light irradiation to produce visible light. Films are capable of multiple cycles (>10 times) of organic photostimulated luminescence, which was still observable from films left in the dark at room temperature for one week after excitation, and emission color could be varied by changing the trap/emitter molecules. These findings will broadly impact existing applications and provide new prospects for innovative flexible devices.

An object of the present invention is to provide a fluorescent probe that easily penetrates a cell and is capable of selectively and efficiently detecting singlet oxygen generated in the cell, a singlet oxygen detection agent containing the fluorescent probe, and a singlet oxygen detection method using the fluorescent probe. The fluorescent probe for detecting singlet oxygen comprises a compound having a silicon-rhodamine skeleton and a skeleton that increases the fluorescence of the fluorescent probe after trapping singlet oxygen to be greater than the fluorescence before trapping singlet oxygen, or a salt, hydrate, or solvate thereof.
