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.
本发明的目的是提供一种荧光探针,该探针可以轻松穿透细胞,并能够选择性和高效地检测在细胞中产生的单线态氧,以及含有该荧光探针的单线态氧检测剂和使用该荧光探针的单线态氧检测方法。用于检测单线态氧的荧光探针包括具有
硅-
罗丹明骨架和增强荧光探针在捕获单线态氧后的荧光强度大于捕获单线态氧前的荧光强度的骨架的化合物,或其盐、
水合物或溶剂化物。
