9,10-Anthracenediyl-bis(methylene)dimalonic Acid is a water soluble derivative of anthracene and is usaually applied as singlet-oxygen probe[1]. 9,10-Anthracenediyl-bis(methylene)dimalonic Acid can be photobleached by singlet oxygen to its corresponding endoperoxide, causing a time-dependent decrease in absorbance at 380-400nm[2]. The absorption, emission and excitation spectra of 9,10-Anthracenediyl-bis(methylene)dimalonic Acid are not pH dependent. No bleaching of 9,10-Anthracenediyl-bis(methylene)dimalonic Acid was observed upon addition of either H₂O₂ or Na₂O₂, confirming that the probe is insensitive to peroxides[3].

9,10-Anthracenediyl-bis(methylene)dimalonic Acid是一种水溶性蒽衍生物，通常作为单线态氧探针应用[1]。9,10-Anthracenediyl-bis(methylene)dimalonic Acid可以被单线态氧光漂白为其相应的内过氧化物，导致在大约380-400nm处的吸光度随时间减少[2]。9,10-Anthracenediyl-bis(methylene)dimalonic Acid的吸收、发射和激发光谱不依赖于pH值。9,10-Anthracenediyl-bis(methylene)dimalonic Acid对过氧化物不敏感，在加入H₂O₂或Na₂O₂时没有观察到9,10-Anthracenediyl-bis(methylene)dimalonic Acid的漂白现象[3]。
