  • Fluorescent probe, singlet oxygen detection agent, and singlet oxygen detection method
    Patent number: 10564164
    Abstract: 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.
